Ball flight laws and off-center hits

What does Trackman say about off-center hits? If you hit towards the hosel, does it make the ball head left more or spin left more? Vice versa for the toe. Does it tell us anything about thin or fat shots that is different from what most people think?

Nothing about thin or fat, no... but I don't know what you'd expect to see there, so I don't know if it's different than what you think most people think.

Shots on the heel tend to start further left and have more fade spin. Vice versa for shots on the toe. More so in woods with bulge and roll but still there in irons.

Ha ha, I was hoping for some earth shattering contradiction of what we all assumed was correct.

They don't? But then how do they roll farther?

Uhm, no. The only thing that can have topspin is a ball that's topped. Hooks don't have ANY topspin. None. Zero.

I hit it 5 yards further when I grunt loudly

Not necessarily. Nor are they necessarily lower.

I can easily hit a fade that rolls out more and launches lower than a draw. Consider a pull-fade versus a push-draw? Which one's hit with a clubface that has more loft? Which will have more backspin? Which will come down more softly? Let's assume there's a club with 30 degrees of loft normally. Let's pull-fade or push-draw a ball 10 yards. - The push-draw will be hit with a club traveling in to out let's say eight degrees with a face open four degrees, yielding MORE than 30 degrees of dynamic loft. The ball will fly higher, with more backspin, and roll out less. - The pull-draw will be hit with a club traveling out to in let's say eight degrees with a face closed four degrees, yielding LESS than 30 degrees of dynamic loft. The ball will fly lower, with less backspin, and will roll out more. There are some small generalizations made there (for example, we're assuming the same amount of sidespin, even though the club with less dynamic loft and the same clubhead speed will put a teeny bit more sidespin on the shot, but it's small enough to ignore.

Please do not debate any topics that involve physics. It's entirely obvious to everyone now that you're incapable of doing so.

I said no such thing. I simply refuted your BS about balls having topspin. ALL properly struck golf balls (putters excluded but not always) have varying amounts of backspin (never 0) and varying amounts of sidespin (rarely zero) and NEVER EVER have topspin.

Yep. To put it in another light, a righty's push-draw could be a lefty's pull-fade.

Now, there are some things that commonly happen in executing a pull-fade (flipping is a big one) that amateurs do that often lead to slices going higher than draws, and it doesn't help that even people like Johnny Miller love to talk about "trap draws" and "going draws" and how the ball runs out more, but the science and logic here is pretty clear - a draw can have more backspin, a higher launch angle, and a steeper angle of descent than a fade quite easily and among better players quite commonly works out that way. Good players often see identical numbers - but flipped - when they switch between push-fades and push-draws, too. I can hit a 7-iron with a fade or a draw and get the same sidespin and launch numbers and the same distances. Again, why do most golfers hit draws lower and with more roll? Because they hit pull-draws. Pulls always go lower than pushes, they have less backspin, and they hit the ground at a shallower angle so they can roll out more. There aren't many good pros who hit pull draws, though. It's a "common golfer" ailment.

I'll tell you the secret to putting topspin on a golf ball. It's all in the grip. Forget about neutral, weak, strong.

The secret is the semi-western grip.

And since you get more spin with a tightly strung racket, you can't get as much topspin on a golf ball with forged metal clubs.
