Speed doesn't change the effective loft. It changes the interaction between the delivered loft and the ball, thus affecting the launch angle.

Why is that a question? Grooves have a larger effect vertically than horizontally.

Sounds fine in theory. But longer clubs are also less lofted - which in turn will compress the ball more too, even holding clubhead speed constant, no? Which would trend in the same direction but for a different reason.

 

Yes, I said that - not the exact way that you did, but as we know, the lower the spin loft the more a ball is deformed - a ball is not really "compressed." It's deformed.

I'm still not sure though whether these effects are "significant" - or if in the real world the effects are so minor as to be negligible.

 

4° is probably a stretch, yes, but the launch angle can and does change because of changes in clubhead speed (keeping all else constant, which MEfree had effectively no chance of doing).

Because I wrote what I supposed you were getting at - but I was hoping you would confirm.

My bad. I lapsed into the vernacular there, didn't I?

Indeed. Deformation. :)
