Direction on the serve

[tpa]

Look at Fed's left hand I am seeing more body rotation on the out wide serve

[John Yandell]

Yeah I see what you are saying but I think you mean in the T serve, which is the top still sequence. I notice for some reason I missed on animation the tight T from behind...I'll get that up when I get back from Indian Wells.

That's what Brian Gordon said as well--more rotation on T--and that might very well be true.
