The beat the song is built on is one bar, played through bars 11, 13 and 15, and 34 more places -- 30.1% 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 and snare, counted in sixteenth notes. On its own it scores 7 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 23 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 65 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 65, 75 and 86 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
