That's why I said it won't happen. Because it's insane for your body. Yagudin quit, Ilia Kulik quit, Yagudin quit<---- all of them are supermen in the men field yet they couldn't do it, I don't think a kid with slender frame like him could do a 4A. Nevertheless, I hope he the best that he could mastered his 4S like his 4T, then 4Lz... that might be more than enough. When he hasn't masted the 4S, he shouldn't think of the next quad.
Because he have slim body it is not so demanding for him, because with more massive body the higher forces working on you, but I don't think he is crazy about that 4A like i must do that, no matter what. I think he is just trying from time to time that. I think when he will have fully consistent 4S he will be propably targeting for third quad in LP as 4Lz
