The beat the song is built on is a 2-bar phrase, played through bars 35-37, 67-69 and 89-95, and 3 more places -- 28.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, hi-hat, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 64 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 79 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 127 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 127, 150, 173 and 196 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
