A guy from Alabama played on my 4.0 team in Iowa and had just gotten bumped up from 3.5 after winning Districts in Alabama. He was a weak-solid 4.0 which is consistent with where a guy would be if he had gotten bumped up to 4.0 in Iowa. Another guy who is still rated 3.5 but plays #1 moved to Florida this spring and played in a tournament there and won his first 3.5 round in straight sets and then lost the second round in 3 sets. Looks like he is a competitive 3.5 down there as well. I have played a top 4.0 from Kansas City and we were even too. So to me it looks like 3.5 and 4.0 ratings are fairly consistent in different parts of the country at least in Alabama-Iowa-Florida-Kansas. I guess I need to play a 4.0 from California to do the west coast test.
