I was researching upgrades and this and that. Came across this:
"If you over pressure any round object it will become unstable. Just the right amount of gas is needed to get the a more accurate shot, sometime less is more."
Anyone have any experience with this?

This is somewhat true and is usually controlled by BB weight and the proper hop-up bucking hardness associated with the fps. When using a higher power the weight of the BB should be increased. A heavier bb assists in gaining more inertia which can result in more range and accuracy because it is less affected by wind and enviroment. There are a few articles on the web about this subject www.airsoftretreat.com/features/articles/fpsweight/ |

more so with hop up..
the spinning creates a boundary layer(think golf ball, and the reasoned dimpled bbs are a joke), if you collapse it by going to fast the shot goes wild..
but this is higher then most people will shoot unless you are trying to snipe with .2s..
for range performance general rule of thumb, balance your bb weight so you don't go past 400fps.. 350 is better.. this is do to drag being nonlinear
there is some bad math in the posted link and results, the author corrected some of it latter..
in a nut shell drag grows exponentially.. so a heaver, slower flying bb that has the same energy as lighten, faster one experiences less drag..
IE stick you arm out a car windo @ 25 mph..now try 50...far more the double the amount of force
your qoute sounds like it was written about classics.. they have very different internal ballistics and tend to be very senstive to BB speed
