The beat the song is built on is one bar, played through bars 1-15, 17-19 and 21-23, and 6 more places -- 32.6% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on snare and kick, counted in sixteenth notes. On its own it scores 51 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 79 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 98 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 98, 115, 133 and 150 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 snare and kick, in 3/4 at 150 BPM, counted in sixteenth notes. It is written out above, and it covers 32.6% of the bars the kit plays.
Bars 1-15, 17-19, 21-23 and 25-27, and 5 more places. The time is kept on the snare to start with, and it changes 23 times over the song.
51 out of 100 on its own -- a step up. The song as a whole is 79 out of 100: demanding, mostly on the independence between the hands and the feet.
