    Chrono rules debate with Bill Mills...

    Okay, before the thread was closed we were having a good debate about chrono rules. I'd like to continue it. I've copied Bill Mill's and my posts on the subject. I know others had good input also, but this was enough work! Please repost your contributions.

    No, he required something that is required.

    The proceedure for chronographing an RT valve paintgun with chronographs in common use today requires holding the sear back with the trigger then releasing fast and firing. This proceedure was defined by Airgun Designs and is accepted by major tournament series (NPPL, PSP, IAO, Pan Am, etc.)

    This method is required to get a reading of the maximum velocity at which the gun will fire.

    Since Frankie "Bag-o-donuts" was the chrono judge on the Shocktech field, and he knows the proceedure, he was requiring it.

    If you do not use this method, the gun will chronograph at a velocity that is lower than the velocity it achieves while rapid firing. The alternative is using a chronograph that can measure the velocity of individual shots in a string. Due to cost and complexity, these are not in common use at most paintball tournaments (NXL is now using one) which is the reason AGD developed the hold and pull proceedure for the RT equipped 'mags.

    To remove the trigger rod makes this method of chronographing impossible, and leaves a situation where a gun that chronos under 300 fps will shoot at over 300 fps during actual game play.

    The problem arose because the gun was modified by the user from its original factory design (a part was removed.)

    I have discussed the trigger legalities of the E-Mag with Bill Cookston, the Ultimate Judge for the PSP, IAO (and previously NPPL) and he's had no problem with the E-Mag trigger, as long as it was not adjusted down to the point where it became a runaway trigger in E, manual, or hybrid mode. As it ships stock, unless fed abnormally high pressure, the E-Mag is a legal gun. The problems arise when players tweak the trigger trying to get it close to the edge of what is legal. Sometimes they go past that edge. It seems silly to me that when someone takes a working, tourney legal gun, and then tweaks it to where it either no longer works (in the case with a lot of 'cocker tweaking that gives the gun a reputation of needing lots of work) or is no longer tourney legal, that they then turn around and blame the manufacturer and or tournament referees for the situation.

    As for Meph's statement that a comparison of AGD to other companies who did have factory techs at the event by someone who didn't pony up the cash to pay for AGD to make an appearance... Why would paying for AGD to make an appearance come into play? The other paintgun manufacturers who did have techs on site didn't require players to pay a couple thousand dollars extra for their techs to be there.

    As to where AGD does send techs, that's their business, IMHO. It doesn't make sense to send factory techs to an event where very few of their customers are. I don't expect them to show up at my local field where there are only a handfull of 'mags. Why should they go through the expense of sending a crew to service a similar number of guns anywhere else? IMHO, the dynamics of their market are changing, and there are probably more effective ways (both in terms of increased sales for AGD, and better support for their customers) than sending techs to every paintball tournament in the US.

    See you on the field,

    And my reply:

    Bill, I must respectively disagree with your interpretation of the rules (and I do have a lot of respect for you). An emag without a trigger rod is legal unless there is a rule against modifying a marker from it's factory configuration then removing the trigger rod in and of itself it legal. Now, the procedure put forth by AGD is an attempt to simulate what can happen during rapid fire with the RT valve. I see nothing in the rules that require this procedure. As long as a modified marker is allowed, it has all the parts that are required by the rules then it is legal. It's up to the chrono judge to chrono it as it could or would be fired effectively on the game field. Want to chrono it as it would be used? Rapid fire and then fire over the chrono. As I understand it other markers increase the dwell during rapid fire (even if not a factory "feature", it could easily be changed by the user). Since the manufacturer(s) have not published procedures for simulating that situation, how do you chrono those markers? How do the tournament directors insure that other markers do not increase in velocity during rapid fire? Because the manufacturer has not stated they will? If one marker is going to be checked for increased velocity during rapid fire, they all must be checked.

    As long as modifying a marker from its factory configuration is allowed, the removal of the trigger rod is legal. The suggested chrono procedure from AGD to simulate rapid fire cannot be required. Other methods of achieving the desired results must be used. If you are going to check makers for increased velocity during rapid fire, then all markers must be checked.

      And Bills retort:

      PSP Rules: http://www.pspevents.com/images/hea..._Rules_2003.pdf
      quote:
      3.25. Players whose markers pass such inspection will step to the chronograph, and the chronograph judge shall chronograph the marker as it would or could be fired effectively on the game field at its maximum velocity. The chrono judge will fire three shots over the chronograph.


      In order to fire an Automag which has a ReTro valve as it could or would be fired effectively on the game field the referee must minimize the time between the opening of the on/off valve and the firing of the shot. This is necessary in order for the air in the accumulator to still be hot from atabiatic compression (the pressure will be higher when it is hotter) and deliver the maximum velocity under the gun's current settings.

      Airgun Designs has defined the proceedure for chronographing 'mags with the RT and published it both online and in print:



      The proper proceedure according to Airgun Designs for chronographing an Automag with an RT (ReTro, E-Mag, X-Mag, etc.) valve:

      quote:
      To record your highest rapid fire velocity:-
      Fire a paintball and hold the trigger back.
      Then release the trigger completely, and fire the next paintball as quickly as possible, once again holding the trigger back.
      Repeat as necessary.
      This procedure will simulate rapid fire, thus recording your highest possible rapid fire velocity.


      To remove the factory installed trigger rod makes it impossible to perform this proceedure properly. If the paintgun can not be chronographed properly, it won't be allowed on the field.

      Similarly if another paintgun of any other brand were modified in a way that the judge knew that they could not get a chronograph reading to accurately reflect the velocity "as it would or could be fired effectively on the game field," it would not be allowed either, whether that modification involved removal of a trigger rod, a velocity lock, changing of dwell times, etc. The rule does not need to specify trigger rods, because it specifies the way the gun can be fired on the field, and AirGun Designs has clearly defined the proceedure needed to measure the velocity to accurately reflect the velocities their product can achieve on the field.

            In the RT chronograph procedure manual, it is mentioned, "At lower input pressures, all benefits of the fast recharge regulator diminish and the regulator acts like the regulator on a 68AUTOMAG."

            Now, we all know that the AIR valve does not require any special chronographing procedure because its recharge rate is slow enough that it can't get shoot-up.

            So, with that, would it be possible to ammend the chronographing procedure and say that those with inputs of 650psi(example) or less do not need to chronograph in mechanical mode? Granted, you do run into issues of gauges being off, especially micro-gauges and most people run preset tanks to begin with.

            Since I really haven't seen it being discussed, I thought I'd bring this up since some people are acting as though the RT valve needs to be modified to eliminate the fast recharge rate so it can be chronographed without the trigger rod.

              I run my X-mag at about 650 psi input and if you hold the trigger down before firing it actually shows a slightly lower fps than just pulling it in electro. In general though with my gun it doesn't seem to make much difference to FPS however you chrono it.

                BlackVCG, thanks for including your post.

                Manike, others have also suggested using a lower input pressure to solve the "trigger bounce" problem. It appears to be a workable solution.

                As I remember you have had opinions on tournament rules in the past. Care to weight in on this debate?

                  I started the thread that was killed so I guess I can comment on this,

                  I have my trigger adjusted the way I like an electro;
                  almost no pull (using TKs quarter measurement, I am under 3/4 oz). there is NO WAY to eliminate bounce with that trigger rod in place and still make the levelX bolt fire when the gun is in hybrid/manual!!! Believe me I have tried everything. I do not care what your input pressure is it CAN NOT HAPPEN. (at least with the emags on our team: one TL63 trigger and two stock) Maybe with 5 magnets, but before that I would use a spyder!!!!!!

                  Bill,
                  Great post and thank you!!

                  Hitech,
                  Thanks for bringing this back

                  The question for TK is how can we fix this? I hate to have to get rid on my mag, but now I have to because the rules are eliminating e/xmags from even having a chance. I will not get into all this again but.. The emags can not compete in this league without a rule change. After I buy my angel I will contest all e/xmags that walk on the field for one of two: over velocity or reactive bounce. The E/Xmags WILL fail one or the other. As the old post said.. The mags need an overhaul for us pure tourney guys, or they are useless!!

                      This is only true if you do not have a levelX if you do the pressures need to be too high to eliminate this bouce effect

                        If I walk up to the Crono station with a marker that has a trigger that responds to one ball = one pull... and I shoot three shots over the crono and they are less than 295 (doesn't matter how erratic.. that's my problem) and when I come off and it shoots below 300... I passed. According to all those rules. And if it's not optimal or not consistent then that's my problem on the field. I would not prefer it but I would take that over having to be out or not use my marker. But no Ref can tell me I failed to meet the rules. NO REF can. It's not in there and its not required that I have a trigger rod. No matter what is "Optimal" and no matter what is "Proper Procedure" according to the manufacturer. THOSE ARE NOT RULES! It's not require I follow that procedure. I can use any procedure I wish to pass without changing things on the field. Nor has ANY organization adopted those as RULES. Nor is it required I be consistent as long as I am not excessive. Nor am I required to DO ANYTHING but pass the rules limitations. And this does not include a trigger rod. THERE IS NO RULE TO REQUIRE A TRIGGER ROD TO DO THIS!!

                        Point set match fella's. Sorry but all of this is not going to change that fact. You can argue all you want. But an Emag is not requred to have a trigger rod. It can be made to pass crono under ANY rules I have seen without one. I admit that its not pretty when set up this way... but it can indeed do it. It's not preffered and not at it's best...but it can be made to pass. And will take the field LEGALY by the rules. And should take the field, as it meets all the rules. It's the rules... and they are blind to all this "Special procedure" or "best way" you seem to set so much store in. And rules, like justice, should be blind.

                          There are no rules stating that I can't over fill my tank. Should I fill my 4500psi tank to 5500 at IAO? Even if it's not specifically in the "Rules" it is the proper way to chrono the gun. Just as stated above, there is nothing in the rule book saying that I can not over fill my tank, but the manufacture suggests not to.

                            Actually, doesn't the DOT govern that area? The tanks are rated to a service pressure of 4500psi as stated by a government agency. To me, that's a rule. May not be written into tournament rules but a rule none the less.

                            just my $.02.

                              I run my E-Mag at 650psi input and have no problems with it keeping up on the field.

                              Be sure that you are running the LOOSEST carrier/o-ring fit possible. You should be able to hold the bolt at the top of the PT, drop it and it should come all the way down and hit the bumper. If it doesn't, you have too tight of a fit. Keep trying different o-rings until you get the perfect fit.

                              Also, I use ample amounts of DOW33 grease in my gun to keep things from drying out. As with anything else, if you don't keep it oiled/greased, it won't perform like it should.

                              If you are coming to the IAO, come by and I'll give you some pointers and we'll see if I can get your gun working like it should.
