This is only an idea - it is not supported by mathematics or physics only what I know - which is GCSE grade maths and physics.
Seeing as the superbolt is a lot lighter (1/3 or so) than a normal stock bolt - it shouldn't require as much force to get up to the required speed and force. I know the currect A.I.R. and RT valves are capable of being turned down to get more efficiency but they were not designed for this.
Maybe AGD you could re-engineer a valve so that it will work as efficiently as possible with a superbolt giving more shots (which i would love) and possibly a lower pressure (though not that needed it would be nicer to have a less harsh marker, and give me the chance to use higher grade paint).
