The beat the song is built on is a 2-bar phrase, played through bars 31-38, 47-54 and 71-76, and 3 more places -- 20% 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, snare, high tom, mid tom, floor tom and kick, counted in thirty-second notes. On its own it scores 81 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 93 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 73 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 73, 87, 102, 117 and 132 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 31-38, 47-54, 71-76 and 142-149, and 2 more places. The time is kept on the toms to start with, and it changes 20 times over the song.
81 out of 100 on its own -- hard. The song as a whole is 93 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
