Yoda, please elaborate on two points in the takeaway:

1. The difference between the hands turning to the plane for horizontal hinging and for angled hinging
   
   
2. Tracing the planeline - in another thread EdZ (I think) mentioned that you can choose to trace the footline (if it's square to the planeline).
   If you (at address) point your right index finger down, it points closer to the footline than to the planeline. Is it a valid option to trace a line parallel to the planeline, if it makes it more "visible"/"clear" to the player (and the right forearm remains on plane)??
