There were two self-rate in the 5.0 league this year and I played one doubles match with him, and played twice against the other in doubles, the other 2 doubles matches played with a player who just appealed down to 5.0.
Last year 1 new self-rate who played again this year.
Lack of players, playing league is a huge issue, so same team continually goes to sectionals, so sample is small.
