The beat the song is built on is a 2-bar phrase, played through bars 14-16, 18-20 and 22-24, and 6 more places -- 31.8% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 23 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 37 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 62 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 62, 73 and 83 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
