Sorry didn't reply earlier, was busy with things.

@BenG:
Really? You would ban someone from whatever you were hosting for taking actions not to hurt someone. What would you say? "You didn't shoot him at full power. It should have made him bleed at the range, and it didn't make him bleed. Get off my field!" And would the victim complain, "I expected that to hurt alot, but it didn't. Please ban"? I completely disagree with the way you would handle this.

Don't worry, I'm quite familiar with basic physics. I said to decrease BB weight to decrease energy due to the effect of joule creep as ThunderCactus references later in the thread. Losing range and accuracy is fine, since the purpose is for transitioning to close range. Also technically, it's not the impact energy(J) that does damage, it's the impact power(J/s). Like how a push does less damage than a punch with the same energy. So from that, the article which I read along time ago now stating very high fps with similar energy does more damage, seems to make sense. For projectiles which penetrate its target, the terminal ballistics is alot more complicated and involve a balance with momentum.

That 30 feet would be quite useful if the target is 30 feet or less out of range, especially if I'm in range of that target. It would be great if I could easily transition between a gun like yours and his. Also, I haven't sold anything.

@Crowin
Quite quick to jump to conclusions there, yeah? What exactly leads you to believe I have a scary lack of knowledge? Or, what have I said that's incorrect?

@ThunderCactus
Just to clarify, is the point of a chrono test at a field to find the muzzle energy you will be shooting for the duration of the game? Or, is the point of a chrono test to make sure the muzzle energy is within regulation for the duration of the game? I feel it makes the most sense that it's the latter. Correct me if I'm wrong. Additionally for GBB's, is the purpose of the spot check to make sure the muzzle energy is the same as before or is it to make sure the muzzle energy remains below the regulation?

Not exactly, if upstream pressure is constant, downstream pressure can still be decreased or then increased back to upstream pressure, though it can't ever be increased above the upstream pressure. Even though FPS can change, the upstream pressure sets a max FPS.
