I was actually aiming for something even more difficult. A response based on your own experience. What separates your best shots from the rest?

My own experience? Hmm

It's a little like the lottery. I can tell afterwards if the shot was good or not, but I never know what's coming.

My own best drives are when I have less OTT, steep out-to-in downstroke and instead get a more rounded backswing, extensor action without swaying and a loose enough left wrist to get a left arm role thru the ball.(Is that the same as horizontal hinging?). And swing thru to a full finsh.

Sometimes it works ok and sometimes not so ok.
