And of course, no Manufacturer would ever want that display to give, oh say, the shortest time between two registered shots instead of the actual number of shots fired in one second would they?
Sorry dude, but shooting 15bps unaided (no bounce/ramp/added shots) is VERY difficult - I only know a couple of freakish people that are capable, and even then only for short bursts (I manage 11 tops)
But hey - you can believe what you want, cos that's your right. Just don't ever test your gun over a PACT chrono, cos you may be disappointed.
