Hi all. I'm interested in the swingbyte but am getting a little lost in the numbers. Not I don't know what they mean, more to my eye they don't seem to be adding up. If the swingbyte knows the target line purely from where it's pointing at address (which is my understanding) and records the difference in club face from address to impact, the club path as a difference to the target line then lastly the club face to path, then the numbers would all add up, surely. Taking the example on the website under "view your swing data" here http://www.swingbyte.com/tour it says club path 4.8 in-to-out, club face to path 2.8 open but then club face to address 2.8 open. Sorry but this looses me. If the swingbyte gets the club path from the club face at address, it swings in to out by 4.8 through impact and has the club face 2.8 open to the PATH at impact then surely the club face has opened 4.8 + 2.8 degrees so 7.6 degrees open when compared to the club face at address. If the club face was open by 2.8 degrees from address and the club is swinging in-to-out by 4.8 degrees compared to where it was facing at address, then surely the club face is closed to the swing path by 2 degrees - nice little draw. This seems to be the case on every set of figures I've seen so surely I'm missing something - could someone enlighten me? Clearly I'm missing something.
