I don't doubt that, and I believe you - but put it against the shot-timer and put up the vids. Mine are over here, in this thread right now:
I'll be back out there, especially now, getting "back in shape." Last summer, I was consistently pulling 0.11 and 0.12 seconds between shots. Those vids I just put up in there are after not shooting like that - at all - since last summer. I pulled alot of 0.16s and 0.15s, occasionally dipping down and hitting a 0.14 or so. 15 rds in 3.08 seconds, if I can keep it up, is 6.16 for 30. That's with mostly 0.15s and 0.16s. In practice, I should be able to get sub-6 seconds for 30 rounds. Just like your trigger.
By the way - welcome aboard. <thumbsup>
