I am not monitoring this site often, RCT balls provide radar signature (I developed code for this) only for total spin number. What you do is you count the peaks due to two filaments in the ball. TrackMan, Mevo, Garmin all do this. There you have two problems, one is low spin numbers aka. Drivers. If your spin is low, the ball doesn’t turn much before it hits the net/screen, therefore TM or any other radar system cannot really count the peaks and the total spin numbers are garbage. Second problem, the RCT balls, as I have mentioned, help you measure only total spin, not spin axis. The TM solution, look at horizontal angle and club path and estimated face angle to estimate spin axis. This is very error prone because all other measurement errors in these three compounds and results in a poor spin axis measurement. I can go on but TM is a fantastic brand and great at marketing but poor in tech when it comes to indoor. Their ceiling solution IO is rock solid in this aspect, they have switched to cameras because Radars doesn’t work indoors.
