The beat the song is built on is one bar, played through bars 1-52 -- 28.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on the hi-hat foot, counted in sixteenth notes. On its own it scores 0 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 57 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 99 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 99, 116 and 132 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
