The beat the song is built on is one bar, played through bars 29-64, 80-175 and 191-210 -- 72.4% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 57 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 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 117 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 117, 138, 159 and 180 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
