It's simply not plausible to keep stats like confirmed kill, otb kills, anything involving individual stats. A good amount of the time, if not the majority, two or more people are shooting the same lanes and it's hard to figure out who shot him when our coach the people shooting the lane and the person who got shot talk about it afterwards.
So here's my idea, the technology doesn't exist for it right now and it may never exist but here goes:
First players where a kind of body suit underneath their jerseys that covers them entirely. This suit is electronically wired to detach when the force of a paintball hits it and then send that information to a head ref in a booth, who with this information can deactivate the gun of the person who's playing. You could ensure that sliding or other impacts don't read as a hit if you can isolate some average amount of force a paintball hits result in and the small surface area it affects. However as a draw back, bounces would probably count in tournaments and I'm sure people would hate that. The suits, sensor system would eliminate a great deal of cheating and leave on field refs to focus on mask, pack and hopper hits and they'd be able to distinguish exactly when players were shot during bunkerings in exchange. You could finally tell who was telling the truth when they yell "I shot him first." Obviously this would take forever to put into affect but I think 4-5 years down the line it would lower cheating to a level that doesn't effect the game to as greatly as it does now and eliminate bias. Watch Ollie Lang play and tell me he doesn't get the most gracious calls in paintball.
In terms of stats it could really narrow down who shoots who, you could get the precise time someone got shot, and on video you can isolate who was shooting that way at that time and make a much better assessment of who did the damage. Since were talking about a hypothetical years away, it's pretty safe to assume resolution on cameras would be much better and you may even be able to capture each stream players shoot from an above angle camera.
In the future I think paintball should be played on a kind of sunken field, as in the way football stands in the pros are 15, 20 feet above field level. I think the ideal view for watching would be from above as if looking at a chess board. If these pressure sensor magic suits existed cheating would be reduced greatly, stats become easier to handle as well and I think paintball would be much more legitimate.
Well there's my rant, take it for what is, criticism's welcomed.
