it's all about the tennis and there are times when comparisons are most apt. like looking at the way the Young'uns are doing so great over at the WTA while the Old Balls are still going strong on the ATP. or looking at the differences in the approach to ranking. or seeding, or salaries, or length of match play. there are lotsa bases for comparison even if they are different tours. comparing them doesn't have to mean that we expect them to be identical surely? heck even players on both sides of the divide make observations about each other. why shouldn't we?
