Advanced Analytics for SkyTrak data - would appreciate feedback

No, that’s the key: for a given HLA and sidespin rpm (spin axis factored by total spin) number, there is theoretically only one combination of face and path that will produce it (again assuming no gear effect).

I'm not sure I follow. My example (+7 degrees path, -1 degree face) will read zero spin axis, zero side spin, and zero HLA, just the same as zero path, zero face would. Thus theoretically, there are infinite combinations that will produce a given HLA/side spin. Or am I missing something?

Anyhow, very impressed with this effort. Very professional.

Thank you! Appreciate the feedback.

This is really cool! Thanks for putting it together, I just took a brief look but there is a lot of interesting data there which could be very useful. Looking forward to exploring more of it later.

Very interesting. What if path and face zero each other out? There must be many combinations of face and path that produce a given HLA and spin axis while still hitting center face? For example path 7 degrees in to out, face 1 degree closed.

Very nice representation of the data. Perfect for club fitting, gapping etc.

Thank you!

The models do a respectable job for path, face to path, AoA, and dynamic loft based on launch angles and spin. For example, given a certain horizontal launch angle and side spin and assuming center face contact (no gear effect) there is only one swing path and face-to-path that will produce those numbers. And it’s the same idea in the vertical plane for AoA and dynamic loft.

I don't understand how it could calculate dynamic loft or angle of attack based solely on ball measurements.

That is pretty impressive! Very cool way to look at each club in your bag.

SkyTrak calculates those numbers based on its measured data, assuming center clubface strike. The club data is in your database, but not exposed in the current version of the SkyTrak app.

Can you explain how you're getting club data? AoA, CHS, face and path??

I built this to have a better view of all my SkyTrak shot data:

If you’d like to try it out with your own data, and you run SkyTrak on a PC, sign up at https://gunghogolf.com/signup and follow the Analytics link in the menu. Full instructions will be there. You’ll be uploading a database file from your PC to my server. (Your analytics page will be private, unlike mine which I’ve opened up for demo purposes.)

Would love feedback! Here’s a screenshot:
