BAM. this is where it's at. People should be chronoing with the weight they will be shooting and muzzle energy should be calculated from that.
It's WAY too easy to cheat a chrono if you know how the gearbox and air voluming works.
You could build a gearbox that would chrono 400fps with .2s which is 1.48J but with a .4 it might chrono something that's 1.7 or 1.8J... I pulled those numbers out of my ass, but it's possible to get higher J with heavier ammo with a setup that gets proper fps/J with a .2
