Digger:
As Homer said, feel like the right wrist never releases....although most will have the right wrist flatten after separation or at both arms straight, if one swivels the right hand palm down to the plane after both arms straight, the right wrist could stay bent all the way into the finish.
Sooo, until both arms straight would be good, strive to never feel the bent right arm flatten, and that will help ensure that at least through separation or both arms straight, you continue to feel the drive of PP#1 and Lag Pressure of PP#3, down, out and forward!
