The beat the song is built on is a 2-bar phrase, played through bars 17-27, 37 and 39, and 2 more places -- 27.9% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 8 out of 100 -- straightforward -- and the thing that decides that is how many notes a second it asks for.
The whole song is 36 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
The room opens this beat on its simplest reduction, at 120 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 120, 140 and 160 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
