Zig-

Thanks for joining in, you will certainly get some resistance, but you have a lot to offer people in spite of themselves.I hope you hang in there and shed some light on things.

Thanks again. Your measurements of xfactor/stretch and speed gains and application at the individual level are breakthrough stuff.

Here are a couple of questions for starters.

The "general" shoulder/arm extension sequence I think I "see" (without the help of motionanalysis which you have so much experience with) is that for inside location the shoulders turn to contact and the wrists unhinge, but there isn't sequential extension of arm/forearm.

For outside, the shoulders turn almost to contact (hiups turn less than for inside), there is some extension/unhinging at the elbow and wrist, but again, not at the shoulder (arm does not extend in shoulder socket in either case before contact).

You have a database of measures on how much the hips and shoulders turn to contact for in vs out/when the shoulders catchup to hips relative to/at contact.

Have you measured this for types like Bonds who get very close to the plate and still keep the inside balls fair by shortening the swing by "hooking" the handpath, mainly by pinching the front scap toward the spine and unhinging the wrist with no extension at elbow or of arm in shoulder socket ?

It seems like some of these hook swings can work with contact after the shoulders turn past the hips such as the 105 degree description Jack gives.

Alos, it would seem to me helpful to use your database to identify high level hitters that a given student would do well to emulate so they are not doomed to failure imitating the wrong role model.

Thanks again, and as you say, Have a positive day !!!
