Trackman, Is that really accurate? - Page 4

post #55 of 59

The impact between clubhead and ball lasts only milliseconds or something like that.

 

The ball compresses against the clubhead itself (deforms)

 

And then the ball shoots out of the clubhead. By the time you feel the impact in your arms the ball is already on the way from the clubface.

400-450 microseconds, IIRC, and the ball doesn't really compress - it deforms, yes. And the ball is long gone, indeed.

very small angular differences, with clubface angle would make the ball into slight fade or draw?

 

Imagine that 0deg clubface is straight shot with a driver. Ball deforms perfectly against the clubface in this scenario presumably, when ball is against the center of the face at 0deg angle.

 

so small clubface angle such as +2deg open, might cause an acceptably accurate fade?

 

would a fade shot cause different deformation, compared to straight shot? What does trackman data indicate? slight fade vs straight

Good thread.  A USGA study showed that most 15 handicappers only hit the drive on average 215 yards.  Most people have an inflated sense of how far they hit the ball.  GPS doesn't lie (oh maybe by a couple of yards).

It's always a matter of clubface and path, and point of contact, and swing speed, AND dynamic loft.

 

You can't simplify things. You can have a face pointed well right of the path with a 9-iron and barely curve the ball, while with a driver at 125 MPH it's going to curve off the planet.

What does this have to do with this thread?
