The beat the song is built on is a 2-bar phrase, played through bars 34-41 and 59-66 -- 15.1% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, hi-hat, snare, mid tom, floor tom and kick, counted in thirty-second notes. On its own it scores 47 out of 100 -- a step up -- and the thing that decides that is how fine the subdivision is.
The whole song is 75 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 68 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 68, 81, 93 and 105 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
