99 bars at 185 BPM -- fast, and 2:08 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot.
70 out of 100: demanding, mostly on how many notes a second it asks for.
hi-hat through bars 1-42, snare through bars 43-54, hi-hat through bars 55-63 and snare through bars 64-99.
The beat the song is built on is a 2-bar phrase, played through bars 10-41 and 80 -- 33% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

185 BPM, in 4/4, with the time kept in thirty-second notes. At that speed the thirty-second notes are the whole difficulty, so the room will take it down to a quarter of it and climb back.
70 out of 100: demanding, mostly on how many notes a second it asks for. The beat itself is 55 out of 100; the rest of the number is everything around it.
99 bars, about 2:08 at the written tempo. The course breaks it into 24 exercises over 11 sittings, about 21 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.
