A 280fps UMP on .25s can outrange a 400fps AEG on .28s
I've seen first hand Amos' team's type 56's outrange his SVD.
And at the open house, my M249 at a mere 320fps managed to somehow outrange most other rifles there!

Heavier BB's give you a huge advantage at higher velocities in both range and accuracy, there's no doubt about that. So how is it physically possible that I can outrange a high fps rifle with heavy bb's with an AEG that has inferior FPS and a lower bb weight??
If everything that touches the air that moves the BB (piston head, cylinder head, cylinder, air nozzle, hop chamber, hop rubber, inner barrel) are of good quality and seal really well, you'll have an amazingly long range and accurate gun. Good compression = laminar flow, bad compression = air leaks = turbulent flow.
I'm not saying FPS has no effect on range, I'm saying it's significantly less than people think. Having good compression is more important than high FPS.

People used to think everything fell at the same speed. Until someone figured out how to build a structure more than 200 feet tall. All of a sudden heavy things hit the ground before lighter things. WITCHCRAFT!
All your theories, fancy math, big words, university level calculus and small difficult words mean nothing in comparison to actual field trial
When you say outrange, do you mean the BB literally goes farther? or more effectively to a farther out distance? was the hop up set perfectly for each of these BBs? Were the guns using the same BBs? Same weight? Same brand? Were they tested side by side? were they tested on different days?

Because your claims raises a few questions.

Your claims literally break a NUMBER of laws of physics, especially those of newton's(gravity constant), AND acceleration. From a purely on-paper perspective, your claims can be instantly dropped as bogus claims. And please do not disrespect laws of physics. They are not THEORIES of physics, they are LAWS, meaning they have been proven, for hundreds of years. Without these laws your airsoft guns would not exist.

Like both I and m102404 have said, compression is purely for consistency purposes. They do not affect the flight distance of the BB. Yes, it will increase the EFFECTIVE range of your rifle, but not the pure distance like you claim. It will affect the flight distance only if better compression has achieved higher FPS. This has been proved in ATP.

When I first read Airsoft Trajectory Project, it was great because it proved many things, such as heavier BBs went farther, and these were real life testings. I believe BB Bastard hosts them because they prove something, and are extensive studies with constant control factors. In that sense, with the proofs and testing, ATP's claims of improving pure flight distance(FPS, BB, and hop up) is much more credible and believable because ATP's extensive testings and proofing backs it up. Now if you dismiss these proofs and testings as "Your fancy charts means nothing" and go on only to write a few words of your "witnessing" with no proof, writing a theory that breaks laws of physics, and disrespect, personally I believe you lose a lot of credibility for me. Because you are not giving a single bit of respect to your opposition's proofs and testings. On top of that, it's such an adolescent thing to immediately dismiss any findings disproving your beliefs.

But like I said, you're emphasis on Compression is good. After all, what's the point if you can shoot 200 feet but can't hit a side of the barn right? So you need consistency, and compression is a great way to achieve that. But for purely distance applications with ignorance to consistency and accuracy, it's FPS, BBs, and hop up.

So It's not always "my way or the highway"

just my 2 cents.
