Last quick update...I don't have a chrono that does a bps measurement, so I did it the super-scientific way: shot two hoppers worth of paintballs and timed it.
First, I adjusted the r/t to dry fire as fast as I could get it to go while still maintaining a sweet-spot that I could consistently maintain.
The first hopper emptied in just under 18 seconds. Roughly 11bps, including a couple of stutters on the trigger. So my max is (I'm guessing) a few bps higher than that...I'd be comfortable calling it 15bps. The second emptied in 20 seconds, but I was at the tail end of the tank and it wasn't feeding well for the last ~20 balls or so. This was on a freshly-filled 47/3000 hpa tank...so I answered another question for myself - I can get around 380 decent shots out of that tank.
No chops at all, just a couple of barrel breaks because of old paint.
