Actually, the more I think about it, it would make much more sense to make dynamic ratings available. There is a lot of upside and very little downside. On the upside: 1) It would make it easy to ensure more competitive league matches, court positions could be assigned according to dynamic rating. 2) It would allow people to quantititively measure their progress as they improve. (Hey, I improved from a 3.42 at the beginning of the year to a 4.19 at season's end - sweet!). 3) The system could even allow for separate ratings for singles and doubles. (Hey, I'm a 5.1 mixed doubles player, but I'm only a 4.7 singles this year!). 4) You would be able to know how tough your opponent is going into every match. Downside: 1) Easier to cheat (I'll make sure I stay at 4.499999.) Personally, I think this a stupid reason to keep dynamic ratings secret. What do you think?
