Homer assumed Separation to be at Low Point but what if it isnt?

Makes sense, thanks.

Hinge Action irrelevant in what context? Surely you dont mean irrelevant in a general sense. The effects of Hinge Action can be clearly seen in the simplest of shots, a chip shot for instance.

I like what little I know about Trackman , dont get me wrong. If it doesnt measure it as of yet, I'd imagine it will in the future.

No, Hinge action is irrelevant in terms of trackman or D plane measurement.

I would highly recommend reading some of their(trackman) newsletters. Very interesting stuff.
