I've pondered over this for a while... I've been thinking in general that I should get every return back into the court, and on second serves get in closer and hurt the opponent (or at least do more with the return). But at the same time I want to be aggressive and get as close to the baseline as possible to take the opponent's time away, which generally is a riskier play because the trade off is consistency. So to be consistent, I have to back up a bit to give myself a little more time to line up the ball onto the strings cleanly. So I wanted to see how far everyone stands behind (or on/inside) the baseline to return a first serve that's clear over a 100 mph (100-115 range?) and placed well. If you could roughly list both position of the feet at contact as well as starting position, that'd be great, but I think contact is a bit more important, since usually most people start off a little behind that anyways. I'm currently around 5 feet behind the baseline starting position and 1-3 feet behind during contact. Used to be 1-3 feet inside during contact and 1-3 feet behind starting out.
