I think some people take it personally when I say Texas and maybe Cali and Florida are a different level than other states. Look, I am not saying you are bad or whatever, I even said the guys in the video are legit 4.0. But, I stand by my opinion that they would get blown off the court in Texas at high level 4.0. The mix of tanking players, and there are armies of them, keep the best 4.0 legitimate players from ever getting bumped up to where they should be, so there is layer of 3.5, 4.0, and 4.5 tankers in Texas keeping the best real players at 3.5-4.5 from getting bumped up. This is in teamtennis, they don't bother with tournaments that are individual doubles teams or singles. The tankers stick to combo, mixed, team etc.
It's not an insult or a brag, but it needs to be said in order for my opinion about where a player would be rated where I live to make sense, otherwise my opinion will be misunderstood. Yes, plenty of Texas 4.0 would destroy the OP video participants at singles.
