The beat the song is built on is one bar, played through bars 45-51, 53-54 and 78-80, and 5 more places -- 19.2% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
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 68 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 125 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 125, 147, 170 and 192 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
