Thank you for writing this post! It expresses something I’ve thought about for a while which is that the amount of swing understood as the amount of curviness of a trajectory can’t be described merely by release point, pitch point, and interception point data. The same three points can many different curves intersecting them. I think people maybe started using degrees for spin bowling and seaming deliveries and just decided to use it for swinging deliveries as well.
