The beat the song is built on is one bar, played through bars 26-27, 29-32 and 34, and 6 more places -- 19.8% 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, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 65 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 82 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 85 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 85, 100, 116 and 131 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, hi-hat, snare and kick, in 4/4 at 131 BPM, counted in sixteenth notes. It is written out above, and it covers 19.8% of the bars the kit plays.
Bars 26-27, 29-32, 34 and 36-37, and 5 more places. The time is kept on the silence to start with, and it changes 7 times over the song.
65 out of 100 on its own -- demanding. The song as a whole is 82 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
