The beat the song is built on is one bar, played through bars 2-6, 8-13 and 15, and 9 more places -- 21.4% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on hi-hat and snare, counted in thirty-second notes. On its own it scores 11 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 59 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 48 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 48, 56 and 64 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
