The beat the song is built on is one bar, played through bars 5-7, 9-11 and 13-15, and 4 more places -- 37.9% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, ride, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 58 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 68 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 59 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 59, 69, 80 and 90 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, ride, snare, kick and hi-hat foot, in 4/4 at 90 BPM, counted in sixteenth notes. It is written out above, and it covers 37.9% of the bars the kit plays.
Bars 5-7, 9-11, 13-15 and 17-19, and 3 more places. The time is kept on the silence to start with, and it changes 9 times over the song.
58 out of 100 on its own -- a step up. The song as a whole is 68 out of 100: demanding, mostly on the independence between the hands and the feet.
