The beat the song is built on is a 2-bar phrase, played through bars 13-19, 21-28 and 46-52, and 1 more place -- 23.6% 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, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 60 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 76 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 94 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 94, 111, 128 and 145 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
