Didn't a paintball site conduct a hopper test though (i believe it was warpig.com but i may be mistaken) and find that the max bps achievable is around 17. They also did all funny theories using loads of physics equations and complicated stuff stating that due to the weight of the paintball it couldn't theoretically fire any faster than about 20 due to the force of gravity. The marker may be able to fire up to 30 woteva, but the hopper won't keep up and certainly the player won't be that quick.
