One of the luckiest things that ever happened to me is how I found science through scientists.
Fredrik is at the top of that list.
We talked at length this morning about all things TrackMan, and I got some several great answers and insights.
#1. TrackMan reports a clubface angle that is well inside 0.4° accurate.
#2. TrackMan reports an angle of attack that is inside of 0.4° accurate.
It measures the bottom part of the golf swing for things like angle of attack, swing direction, and swing plane. He said, "We take from 7:30 to 4:30 and we measure that path of the club;s center of mass very accurately. The hardest one to get dead on all the time is angle of attack, but we get that within 0.4°."
The measurement for Angle of attack is determined by the plane angle, and direction, and like Fredrik said. "We know precisely when impact occurs on that arc, that is where we get the angle of attack measurement."
The reason AofA is so hard to get closer, is the fact the the path of the club is changing 0.8° during the impact interval. The radar sees around the clubhead, and knows when impact occurs to within less than half of a half a millisecond. He still feels that one day they will get even closer.
We also talked about the incorrect statements out there in web-land, and that TrackMan gives "bad" numbers on off-center strikes.
Not so, says Tuxen. "When the ball is hit far from the vertical center of gravity of the club, it twists in the way you (BMANZ) talked about in your 'It's Math' video. The face angle number reported is very accurate. The confusion lies in the gear effect that takes place which has the effect of changing the spin axis from what it would have been on a center strike."
For guys like myself, Kevin Shields and other users of the device, that is a well know fact. But there are always those who seem to not want the machine to be as accurate as it is.
"We are always trying to get better," said Tuxen, and that gives us something to do always."
Maybe that's why me and Fredrik get along so well, that's my credo as well.
