The beat the song is built on is one bar, played through bars 20-22, 24-26 and 28-30, and 18 more places -- 38.3% 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 63 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
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 102 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 102, 120, 139 and 157 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
