The beat the song is built on is one bar, played through bars 44-59, 82-97 and 110-141 -- 45.7% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 54 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 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 108 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 108, 127, 147 and 166 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
