I wouldn't say easy. It is just yuzuru as a skater has improved and grown a lot this season. I think sometimes we forget he delivered 5 clean programs this season and focused on his disappointing free skate at worlds (which resulted in his losing the title again to Javi). With that kind of technical difficulty this is really a feat. I meant even if we compare to other competitors this season (correct me if I am wrong), patrick has 1 clean SP and 4 (?) clean LP (2 of these were at nats), i don't think javi performed a clean SP yet and world FS is his 1st time performing a clean free? Shoma yet to perform a clean SP (?) but had 1 clean FP, boyang had 2 clean SP, and 1 or 2 clean FP (I forgot). It is just that everyone (his fans, himself, his coaches, the judges, commentators, critics, skating fans in general) has such high expectations on him nowadays, moreso than other skaters.
That said, I do think it will be good for him to do 4 quads in the LP. Everyone else is upping their game next season. Patrick adding a 4S, shoma is landing 4F and 4Lo (he did say he will add another quad and he can do 4 types of quads by now) and who knows what will boyang do. This season is just the season to go crazy and experimental. Oly season will be too risky to have extreme changes in layout. However, I am also concern about injuries, so I am not so sure about how I feel regarding 4 quads.
