chronographing my new RT valve

[Schnitzel]

i've read all the info about my RT valve, and i'm going to be using it tomorrow at SCVillage. The refs/chrono-people are accustomed to just taking the gun and shooting it over the chronograph. how should i go about explaining to them that it takes a different procedure to chrono it?

should i just say "shoot and hold the trigger, the shoot and hold as quickly as possible...keep repeating."?

any other suggestions?

I'm pretty sure that you wouldnt have to worry about anyone at SCVillage not knowing thier stuff.
