The beat the song is built on is one bar, played through bars 18-24, 34-41 and 58-64, and 6 more places -- 52.3% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, ride, snare and kick, counted in sixteenth notes. On its own it scores 61 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 73 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.

61 out of 100 on its own -- a step up. The song as a whole is 73 out of 100: demanding, mostly on how many notes a second it asks for.
