The beat the song is built on is a 2-bar phrase, played through bars 34-38, 40-46 and 88-92, and 1 more place -- 16.6% 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 snare, high tom, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 49 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 66 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 88 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 88, 104, 119 and 135 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 34-38, 40-46, 88-92 and 94-100. The time is kept on the silence to start with, and it changes 13 times over the song.
49 out of 100 on its own -- a step up. The song as a whole is 66 out of 100: demanding, mostly on the independence between the hands and the feet.
