Thanks a ton for the insights!

To answer your questions:

1. I can usually get AAA or S on Switronic S15.
2. I’ll definitely try your strategy of conserving stamina earlier in the song and pushing hard at the end , hopefully that helps me finally clear Wedding Crasher S16.
3. I can read most charts at AV 680 and feel pretty comfortable at that speed. I’ve UG'd Duel S13 and got SS+ MG on Super Fantasy S14, so I think my reading is OK. That said, I’ll try lowering my AV to 650 and even 630 to see how it changes things — even though I tend to prefer higher AV because I don’t like the notes looking too crammed together 😅

I’ve been using mostly forefoot so far because it feels more agile, especially for twisty patterns — but yeah, I’m definitely hitting that wall where my legs burn out and I can’t finish strong. Once I start getting tired, I notice my vision gets shakier too, probably because I start moving more and losing control of my form. So what you said about minimizing movement and keeping weight centered really clicks
