to check if throw is full or not you need to see if your torso made a full turn
semi throw when you pull opponent and pin him on the side and he face same direction as you semi-throw.rpl
full throw is when your opponent face opposite direction. more like 69 ;) full_throw.rpl
this is the difference between full and semi (half) throw
full throw when one arm is up and another is down, then you rotate to another side and change arms, in the end you and opponent face each other in 69 manner ;) full_throw_orthodox.rpl
very rough idea of what it is change arms and full torso turn
