The beat the song is built on is one bar, played through bars 1-14, 16-30 and 33-35, and 5 more places -- 45.4% 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 and kick, counted in sixteenth notes. On its own it scores 49 out of 100 -- a step up -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 66 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 84 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 84, 98 and 112 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
