Tennis is not about winning individual points, but about stringing points together to win games (and sets). I find that first-serve faults tend to happen a lot in the same game. I think employing this "two first-serves" strategy and double-faulting a few times in a game could cost you a break of serve and lose you the set. Winning more points on average over the course of the entire match doesn't necessarily help.
