If the golfswing is an art, then don't use scientific words incorrectly to describe your personal interpretations.
Science is basic and universal, provided it's correctly applied by qualified people. TGM was total rubbish scientifically, and that's what I explained to Brian in 2003-04 when I posted as 'Horton'. Check the archived postings and it's all there.
My point is that even if you had the correct science it is still an art to transfer that knowledge to application.
As we all know feel and real are not the same especially in the golf swing.Science provides the reality of what is happening but that doesn't necessarily correlate with what we feel.Mandrin bless his soul,talked about snapping the kinetic chain.So are you going to start intentionally braking your pivot earlier than normal to get more snap?
On the other hand,TGM got the science wrong regarding STLOC but as a teaching method,is it that wrong?It is very beneficial to FEEL like you maintain shaft flex through impact even if science says that is not what is really happening.Like a lot of methods,TGM got the practical aspect right by accident even if it was incorrect scientifically.
I do agree with you that science needs to be applied by quailified people but who is qualified to determine who is qualified?Would that not be also a personal interpretation?
