It depends on what you mean by "clean". Clean meaning absolutely clean? Or not falling nor popping jumps? Shoma had clean a FS at SA and the GPF (you could even count JO). If you go by the second criteria, Javier had a clean FS at the GPF (he had a turn out on his 4T) and a clean SP at Euros (slight turn out on his combo). And Shoma had a clean SP at TEB.
But I agree, no one had as many clean performances this season as Yuzu did that could balance insane tech, performance, SS, etc. And he was absolutely clean. It's not easy by any means, even for him. But it was only natural that people would have higher expectations for him, given that he showed what he's capable of....twice. And now everyone is upping their game to catch up to him next season, but he always wants to be a step ahead, so perhaps he might consider a 4 quad FS. Though I think that would depend on his injury for the 4T and the general consistency of his 4Lo.
