The question still stands, why sandbag a beginner tournament? It doesn't make sense.
Players have been sandbagging tournaments for years now, which is why local tournament paintball is absolutely dead.
I once saw a team show up dressed from head to toe in camo and using rentals. They were slaughtered all day long. No one offered any advice to them, no one said a word to them. Instead, groups of 19 year olds with about 3 grand worth of equipment attatched to them and jerseys so busy you couldn't even make out what base color they were hovered around laughed and made jokes about how bad they were getting stomped on.
Local grc tournaments have consisted of nothing but rmxl teams the last few years now, teams and players who have national tournament experience...should ask yourself why that is.
