Is someone going to fully explain this, from reading the posts here, I'm confused about what's legal what isn't legal now?
Rear foot has to be perpendicular in both x and y axis now then? shin can't touch the ground?
How will you know if the shin is touching the ground if someone is wearing loose fitting trousers?, How will you know hamster isn't touching forearm with loose fitting sleeves?
Since the rules are largely marshalled by your shooting partners, clear and unambiguous definitions would be a very good idea - some photo's would be even better.
