<Mr. Kelly did his best, but, on this one, he whiffed.>
Exactly correct. HK did some VERY insightful work, particularly for his time. I think it would be hard to learn a great golf swing from TGM, although it would be good source, once understood, to anyone interested in the range of options.
At any rate, great strikers of the golf ball, seemingly in contradiction do NOT pay much attention to the ball except for ball flight feedback. That's why eye hand coordination is almost a bogus subject. You don't dry to correct your swing one way or another to hit the ball perfectly.
Someone might say, "well, you ought to". My reply is "no". The swings the thing. Concentrate on that. And you DO NOT try to swing down an 11 degree alternate line.
