Rotation becomes clearer when you can feel where the turn begins and where it gets borrowed.
Rotation is shared through the feet, hips, rib cage, and arms. A smaller turn that is distributed and controllable often gives you more to build from than a larger turn you have to force.
Begin with a simple reference. Notice sensation, ease, range, and control before trying to correct anything. A clear baseline gives you something honest to compare later.
