The beat the song is built on is one bar, played through bars 17-32 and 49-64 -- 29.9% 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 and kick, counted in sixteenth notes. On its own it scores 20 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 33 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 75 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 75, 88 and 100 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
