in your Mrose reply you speak of 'the only thing the ball knows is impact' i agree indeed.
But, doesnt everthing before impact centralize all efforts and alignments to be inline with the desired impact? i would think so.
TGM is all about maximising effort-physics and correct alignments to get out what you put in. So if the before hand of impact (adress, top, release) is vague, then the impact is not maximised.
I am far from a worthy informer, but i would not spend too much time on the slightly bent left elbow if you are comfortable wiht it, as long as the plane is respected.
Any chance we can get a down the line view?
Any chance we can get a higher speed quality of your swing? you are too darn fast!
