The beat the song is built on is one bar, played through bars 23-28, 30-32 and 45-50, and 9 more places -- 46.5% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 52 out of 100 -- a step up -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 73 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 65 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 65, 77, 88 and 100 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

52 out of 100 on its own -- a step up. The song as a whole is 73 out of 100: demanding, mostly on how much of it falls off the beat.
