The beat the song is built on is one bar, played through bars 28-35, 49-50 and 53-54, and 18 more places -- 34.2% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, snare and kick, counted in thirty-second 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 76 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 112 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 112, 133, 153 and 173 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on crash, snare and kick, in 4/4 at 173 BPM, counted in thirty-second notes. It is written out above, and it covers 34.2% of the bars the kit plays.
Bars 28-35, 49-50, 53-54 and 57-58, and 17 more places. The time is kept on the snare to start with, and it changes 19 times over the song.
61 out of 100 on its own -- a step up. The song as a whole is 76 out of 100: demanding, mostly on the independence between the hands and the feet.
