Metric for inside ski lead

Since you're already tracking boot paths could you calculate the inside ski lead? An even higher level metric would be counter.

This would be kind of like turn closure with an appropriate range for different types of turns and situations.

Been working on excessive counter in my hips and using edging similarity as a proxy but this would be more direct and could include targeted feedback and drills to improve. A monitor mode for this would be great as well.

I think in general, measuring things like this and getting them calibrated by instructors would benefit coaching a lot. Often the places where improvements are needed are currently not directly captured.
