Well, that is MOSTLY correct. You are limited to the field's muzzle velocity limit. Thus your paintball has so much kinetic energy at a given distance. There is a threshold for how much kinetic energy a paintball has to have to break and mark an opponent. A well padded gut vs right between the eyes of a mask requires different minimum kinetic energies to break.
Up to this, all players, markers, and upgraded hardware are created equal.
Some "tournament" paint is very fragile. Drop your paint onto concete and see how far it has to drop to break. Field paint can drop 2-3-4 feet and bounce. True tournament grade paint (just because it says it on the box does not make it real trournament paint) will break under 18 inches.
That obviously requires less kinetic energy to break and thus will break at LONGER distances than field paint.
Of course you have to play where you are allowed to use your own paint or they sell real tournament grade paint.
Then you have to have a marker that will consistently shoot it without breaking in you breech or barrel. Typically a low pressure, tournament marker. Not necessarily a pump which I do not know alot about since the last on I had was a Tippman SL 98 about 20 years ago.
So after you have all that working, you have to go on your quest for Accuracy. Paint is not round and that limits how tight your ball pattern is regardless of your upgrades. If it isn't round when it leave that super duper expensive barrel, it won't fly accurately. Hopefully that tournament grade paint is rounder than your opponents. That is where the modified paintball rounds with fins address that issue. An advantage at the expense of rate of fire.
The critical element from here on is getting the elevation right for the ball to drop onto your opponents facemask. Something HARD to break paint on and usually exposed to shoot at. Very convenient.
So now all you need is the auto rangefinder. You have to make it. Can't buy it. Not too hard, expensive, or requires a lot of tools. Just takes a LOT of time. You did say poor student......... More time than money...
