The beat the song is built on is one bar, played through bars 9-31, 41-55 and 73-79 -- 46.9% 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 hi-hat foot, counted in thirty-second notes. On its own it scores 57 out of 100 -- a step up -- and the thing that decides that is how much of it falls off the beat.
The whole song is 75 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 62 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 62, 74, 85 and 96 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 9-31, 41-55 and 73-79. The time is kept on the silence to start with, and it changes 6 times over the song.
57 out of 100 on its own -- a step up. The song as a whole is 75 out of 100: demanding, mostly on the independence between the hands and the feet.
