Accurate serve placement

[Tight Lines]

Hi all,

I have been searching youtube and other Internet sites to try and improve my serve placement accuracy.

Heath Waters says you should think about two "reference points" . One reference point is the distance of the toss relative to the baseline. For a slice serve, he says to toss further into the court to make the ball go left (for right handers). The other reference point is the angle of the racquet as it strikes the ball, again for the slice serve. According to Heath, a 7pm to 1pm path is the normal slice, 7-1:45 to serve wide (from the ad court), and 7-2:15 to serve to the T.

Well, I am not sure if I can swing with that kind of accuracy. Does anybody do this?

Then, I found this youtube video by JinJin Tennis, which seems interesting.

Basically, he is saying to vary the position of your back foot (assuming you have a platform stance), bringing it left to serve wide (from the ad court) and right to serve down the T. This seems to make sense to me. But the obvious flaw I see is that a good opponent can see your foot and adjust.

So, I was thinking what about if I just kept the back foot in the same spot, but just rotate the foot slightly right or left to do the same thing, which may be harder to detect by the opponent.

Do you think this makes sense? Does anybody do this?
