The beat the song is built on is one bar, played through bars 27-33, 53-59 and 73-79, and 1 more place -- 30.5% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on the ride, counted in sixteenth notes. On its own it scores 29 out of 100 -- a fair first song -- and the thing that decides that is how much of it falls off the beat.
The whole song is 26 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 66 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 66, 77 and 88 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
