Because of the messy patterns that contrast with the slow speed, I think individual differences will be severe, but the twist isn't complex for the level, and since it's basically slow, there's timing to make up for it even if your feet get tangled, so I'll rate it as Mid for now, but I can't shake the feeling that it's Mid-High or close to High. Locals, please be careful with the 16-beat run-like thing at the beginning, and since the video is linked as S10, if you're curious about the pattern, search for it as S9 on YouTube. Maybe because there are no changes even though the level was raised, there are no videos that came up as 10. Looking at the run itself, it's much more manageable than Otada.
