Optimum Racquet Balance for Performance II - MgR/I Data for ATP Pros

[newyorkstadium]

1) Does muscle mass affect the pendulum?

2) You say lead on the butt effects mgr/i for a 2hb. Lead on the butt has minimal effect on mgr/i on the spreadsheet. Does lead on the butt affect mr^2?

3) Why does lead have to be 7" to reduce mgr/i? Why can't it be lower?

4) How do you tune your mgr/i for a backhand. Is there a formula, or do you tune till it feels right? I play ohb.

I've noted that on a 27 " frame, adding lead at 18.5" has minimal effect on mgr/i. Strangely 17.5 " increases mgr/i. Just informing you.
