I would guess I hit the exact sweet spot 1 out of 10 times. Meaning, it feels like a really solid center hit, I don't feel the club face twist even slightly and the ball flies exactly like it's supposed to. Hitting the sweet spot with my driver is one of the greatest pleasures in life. But, like I said, it only happens about 1 out of 10 times.
Two days ago, I hit a 9 iron on a par 3 exactly on the sweet spot and the ball flew high and straight and stopped 6 feet from the pin. Right when it left the club, I said to the guy I was playing with, "That's a great shot." What a great feeling that is.
I won’t do it forever, but having just resumed golf, I’ve been keeping track of a lot of data this year. I’m sure many here would be horrified at my “sweet spot profile,” but at my age/ability/vision I assume I’ll never hit the sweet spot almost all the time like many here can. I was honestly guessing I’m about 50/50, turns out it’s a little better. Might be helpful when I go to pick new irons. This data is all my on course full swing irons only, not woods/metals or practice sessions. And yes, it’s easier for me to hit center on shorter, more lofted clubs than long irons like most/all.
