Problems with Downswing Fitting

We are still trying to improve the results of the downswing curve fitting. A couple of fundamental things that still need work:

• More accurate identification of transition


• More reliably offsetting angles in the downswing by 2*Pi where appropriate

A more experimental possibility we may try stems from the following observation: none of the bad clubhead hypotheses lay outside of the actual trajectory. In fact, there are sometimes many good hypotheses on the actual trajectory that are not in the consensus set of the final model. For example:






Two things that might help the fitting process:

• Weight the fitting towards points with larger magnitudes.


• Weight the fitting towards points later in the swing, because these two images show that most inliers are early in the downswing.
