The guy, who ranges from a crappy blue belt to sympathy black belt, who LOVES to teach, OVER intellectualises, and for some reason - always teaches questionable techniques. It's never, here's a classical standing guard break. Here are the three critical components. It's always some oddball variant that doesn't look practical. And then a ..whole..lot..of..talking.. The white and blue belts don't think twice of it, usually, but the higher belts do.
Why do they always teach (whether it's to cover when the head instructor is gone or off to the side) such oddball techniques? Stuff that I never see them do themselves, mind you. I know of a blue belt who ALWAYS teaches on the side and he always shows the berimbolo to white belts. However, he has never hit a berimbolo live and he teaches it "a little off" anyways (he himself cannot invert very well).
