The beat the song is built on is one bar, played through bars 41-45, 47-49 and 51-59 -- 18.5% 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, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 56 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 69 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 75 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 75, 88, 102 and 115 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
