I know only two people who got bumped down. One was one of my singles players. She started at 3.5 perhaps 5 years ago. Had two losing seasons and was bumped down to 3.0. Played one season at 3.0 and was bumped up. Played singles for my team for two years, going 1-6 over two seasons. Now she's 3.0 again. The other was a 4.0 guy on my mixed team who was bumped down to 3.5. I know of only one amazing result where one of my strongest 3.0 players on my 6.5 combo team didn't move to 3.5 when everyone expected her to. She played and won matches at Districts. I would happily partner with her any day at 3.5. Go figure.
