This is a spin off a discussion on the Men's FS thread. The topic of Jason Brown and his 3A came up.
Many argue that he hasn't mastered the jump because he struggled with it in the FS. But as I point out, he is 7 for 7 in +GOE in the SP.
Which begs the question, what does it mean to master the jump? Does it mean having a certain hit rate in practice or competition? And how would we define that hit rate == 70 percent? 80 percent?
What do you count---ratification (but no fall)? ratification + GOE? Something else?
ETA: Also, how much does executing it in competition comes in to play? There are reports of Yuzuru Hanyu getting the 4S in practice but he's fallen or popped it on 3/5 attempts internationally. Does that mean he hasn't mastered the jump or just that it hasn't clicked in competition?
