Yep. It's really hard not to cheat when you're stuck in that cycle. I wasn't bumped this year but I know next year when I am bumped I won't ever have any chance at that level or the higher level in mixed because our rival club is so strong with their manipulation.
It will be a tough pill because I would have to sacrifice my morals to compete and I don't really want to do that. So most likely I'll just stop playing league tennis like so many others in my community
Or just play and have fun and don't worry about being the best at your level. Sort of by definition, more than half of players are going to be in the lower 1/2 to 2/3 of a level and those players don't reasonably have a shot at winning at States/Districts/Sectionals, perhaps even local playoffs, unless they happen to be on a team with a bunch of upper 1/3 players.
This is just the nature of a system with arbitrary levels. Those players that are naturally upper 1/3 within their level will win a lot and be the ones that go to playoffs fairly regularly. If they improve and have a good year, they may be bumped up, but they may get bumped down naturally the following year. Consider a 4.0 that is naturally right at 3.95. If he plays exactly as expected, he will win a lot and stay right at 3.95. If he plays a bit better than expected one year, he may go up to 4.05 and get bumped up. But if he then plays just slightly worse than expected, he could go back to 3.95 and be bumped down the next year. A ratings variance of 0.1 is entirely reasonable and does not require tanking/cheating/etc.
If the USTA really wanted to be fair and give folks an equal shot at making it to playoffs, they should alternate years where they move the actual thresholds +/-0.25. One year, a 4.0 is 3.51-4.00 and the next year it is 3.26-3.75. Year 1, all the 3.76-4.00 guys are upper half and have their shot to win, and in year 2, all the 3.51-3.75 guys are upper half and have their shot to win. Doing periodic mass bump ups or adjustments sort of does this, but it is really just a one year effect as the 3.80s that get bumped up to 4.5 will inevitably come back down to 4.0 as they aren't really 4.01+ players, they are 3.80s that got incorrectly bumped up.
