While working on this second posting, double checking my data and comparing it against the TOMI data I found again one more problem (and solution) The TOMI assumes that the sweetspot is in the middle of the face. That is normally correct however It also assumes that the sweetspot is at the same height as the middle of the ball. That is not correct.

So the solution would be to also enter face height into the software allowing it to correctly measure impact position.

I found this when checking why my software reported a 10.5mm lifted clubhead and then measured the head. With that 10.5mm lift it would almost been a topped ball. Then I compared the head height with the ball and found that the club used has it's sweetspot around 8mm BELOW the middle of the ball.

so that 10.5 mm topped ball was now a 2.5mm sweetspot miss (below the sweetspot). Big difference!

So what could I retrieve from the data, recorded with this this 75fps@640x480 camera for which I paid Euro 25,- and Euro 5,- for the Infrared High Pass Filter. a few days programming and analyzing around 5gigabytes of data.



It was fun doing this!
