You're on the right path, you just need to refine the test a bit more before you have it right on.
The test I did with my angels (both of them before I sold them off) was for shootdown on long strings of paint (which everyone shoots in tournies, especially the lard butts playing on the back end).
The angel fans were all claiming there was no shootdown in the low pressure nature of the angel, they claimed Tom and that Mag owners were making it all up despite Tom's own test results. I found out through lots of tourny experience with a red dot sight mounted on the angel, I found I was raising my point of aim gradually the faster and longer I fired it to compensate for shootdown. I first noticed it when I was longballing a back player. When I first short 3 round strings, I only needed to put the red dot on the player's head to hit near his waist. When I let the angel rock I had to put the dot over the player's head to hit the same location. This is what led into the below test to satisfy my curiousity. The Angel LCD at the time simply couldn't keep up with the demands I was placing on it. The shootdown was quite real, but since very few angel owners use sights, they didn't readily notice it.
I setup a board (2" x 12" x 5') in the backyard (12 acres of woods to use) against a large oak tree 90' (30 yards) away. I used 10" heavy paper plates that I stapled to the top of the board for the target medium.
The markers (emag and angel LCD) were then setup in a benchrest I use for sighting in my real firearms (both pistols and rifles) on a carpenture's portable work bench that made a very solid testing platform. Both markers were fired at the software limits of 6BPS, 10 BPS, 13 BPS, and then 16 BPS. The emag had a warp feed mounted on it with a modded 12v revy, the same revy was also used on the angel. 100 rounds (1 pod) were loaded into the hopper and fired.
To fire for the test, I used a battery powered dremel tool with a wooden spool with a wooden peg mounted off center in the end, I'd juice the dremel up and bring the rapidly rotating peg carefully into contact with the trigger so that the marker would fire as fast as the software limits would allow.
6BPS: Emag hit the paper plate repeatedly, no visible shootdown. Angel also hit the plate consistantly.
10BPS: Emag hit the paper plate repeatedly, no visible shootdown. Angel hit the paper plate with the first 5 shots then the shots started to drop a bit (visible shoot down) resulting in an oval shot pattern and hitting below the plate.
13BPS (NPPL standard): Emag hit the paper plate repeatedly, no visible shootdown. Angel had a larger of an oval pattern this time and hit further below the paper plate, more visible shootdown.
16BPS: 12v revy had a hard time keeping up, so shot strings were kept intentionally low, I didn't want to chop paint but ended up doing so in the angel several times, which resulted in some crazy curve balls that missed the board completely. The Emag and warp didn't chop paint, and had no problems hitting the plate repeatedly. I threw out the angel results as it couldn't keep up without chopping paint.
If I still had my Angels, I'd love to repeat this test as we now have a loaders that are more then capable of keeping up with 16bps.

). Even, on the Timmy, the consistency wasnt too hot- is that normal for +/-10(or so)? I would hope that any high end properly tuned marker could do +/-2 at least.
