I don't understand why everyone keeps summing up how many times in total each program was performed (also, does it really matter in the end, if it was 17 vs. 18 or 11 vs. 12 times...?

).
A program repeat still equals no new material from a skater in a given season. No matter how often it was ultimately skated.
(sure, if it was just one outing, go ahead and repeat... but if it's been several competitions over the course of a season, be it 3, 4 or 5... then it feels like a whole season and makes me crave something new, no matter the exact number)
Or arguing that changes in the jump layout, a new music cut or little choreographic or transitional differences are somehow making it a different program and reusing it more acceptable.
(wow, if layout changes count as a 'new program', then I know a certain skater who basically has a 'new' program at each competition

)
All of this doesn't change the fact that it's still the same piece of music, the same style being portrayed, the same mood, the same theme... so what if Yuzu adds a few new gestures to Seimei? I'm sure he's not gonna bust out the can-can during its performance...
I also don't understand why it matters or somehow exculpates his decision, when Yuzu has valid, understandable reasons to go back to these old programs. I'm sure he has, why else would he be doing it? Doesn't change the fact that many people will be unhappy with his decision or feel that it still reflects badly on him.
For me personally it just reads like a weakness, clinging to two of his most successful programs like that. It's like admitting that he needs the comfort of past accomplishements and/or can't make other programs work for him (not even ones that feel so similar to his classics and that he's been trying to make work for 1,5 seasons already).
I'm not saying that I believe he's actually incapable of skating new programs successfully, I certainly don't. And if he ends up slaying with his oldies, no one's gonna care anymore about his recycling, anyway.
I'm just talking about appearances and how it's coming across, and I think this is a big part of what's bothering me about it (besides the part where I'm simply disappointed with his lack of diversity).
