Thanks for posting this study information FFS. It is interesting for sure. The last few weeks DD has been working on getting the hips at more of a 45. Her natural tendacy is more closed and we are falling somewhere in-between now which I think works and she is comfortable with. The variations in the best pitchers out there (some pictured above) is proof to me that we are in a good spot and I don't need to jack with it anymore (at least right now).
