I think I cleared it by looking at the all-mo (all-mode) a lot during the inters.

Until just before the late spike, I feel it's closer to mid than mid-high. From the start to the end of the piano part, I feel it's closer to mid-high...

Personally, I cleared this when I was working on my Inter 10.

Despite the "mid-high" difficulty rating, I've seen way too many people clear this when they're grinding for Inter 10.
