Can some one explain how to interpret these measurements. For instance relationship of ball speed, back spin, side spin to carry distance. I realize HMT is needed to truly diagnose one's swing tendency to render solutions. However I would think the GC2 data will provide some clues. Also is there available data charts to use as a gold standard showing ball speed, spin, carry, launch angle, etc. Thanks.
Attachment 52119Here's the gold standard.
Obviously a big pull will show up with L direction. A closed club face will show side spin. Ect ect. Distance is greatly effected by launch angle, ball speed and spin. You can get an idea of club head speed by ball speed. Some will argue things like gear effect but the ball numbers will give you an idea of what's going on.
Exactly as mthunt says.
I'd add that knowing impact location is the missing piece (other than AOA), which can be known by using powder/spray.
I think I've been golfing longer than most, but I can tell immediately from the feel of impact where I struck the ball. Using spray/powder on the face and ingraining what a toe/heel/high/low hit feels like, then you don't need spray.
The spray does have an impact on launch though...spin/launch angle are slightly affected. If you use tape on the face, the impact is much greater.
