62 bars at 165 BPM -- fast, and 1:30 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot.
73 out of 100: demanding, mostly on how many notes a second it asks for.
toms through bar 1, hi-hat through bars 2-16, toms through bars 17-18, hi-hat through bars 19-20, snare through bars 21-23 and ride through bars 24-27, and 6 more changes after that.
The beat the song is built on is a 2-bar phrase, played through bars 2-9 and 19-20 -- 16.1% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

165 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.
73 out of 100: demanding, mostly on how many notes a second it asks for. The beat itself is 73 out of 100; the rest of the number is everything around it.
