The beat the song is built on is one bar, played through bars 17-22, 25-30 and 41-47, and 8 more places -- 48.2% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 86 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 92 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 143 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 143, 172, 202, 231 and 260 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 17-22, 25-30, 41-47 and 57-63, and 7 more places. The time is kept on the hi-hat to start with, and it changes 13 times over the song.
86 out of 100 on its own -- hard. The song as a whole is 92 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
