Here is an interesting case study. Tiger Woods, the worlds best, the greatest champion ever perhaps tbd, with his driver swing out of wack. Nobody , not even Tiger is exempt from bad swing days. ( Note how he is leading the field here, however.)
If you look at his feet post impact he is up on both sets of toes and then standing up through the shot.
His is not a common butt push , left and right scenario. More of an up and down compression as his head and seat move to the ground and back up, maybe. His head bobbing back up to reestablish his radius. A fair bit of movement, eh?
Luke , Drewit et al, what do you make of this? What out of all of this would you change if he called you guys up for a lesson? Or perhaps you are working with him and dont wish to comment.
Still working on my left /right encroachment issues, trying to figure out the dynamics of balance.
Thanks
O.B.
