My wife was bumped up from 4.0 to 4.5, and at first she was upset about it. But after we looked through her singles tournament records (10-3 with no wins over 4.5 bumpees), and singles league records (9-7 with only 1 win over a 4.5 bumpee) we believe that we found the reason. That one 4.5 bumpee that she beat ( 5-7, 7-6, 10-8 ) in league is now a 4.5 benchmark, probably because she was undefeated at 4.0 league playoffs, and undefeated at state... plus this girl played up in a 5.0 league where she won 4 singles matches, and played up in a 5.5 league where she won 3 singles matches. My wife remembers being so thrilled and proud about winning that particular match, that even if it means getting bumped up for it, it was still worth it. (hey, at least she didn't say winning that match was better than sex, right?)
