The beat the song is built on is one bar, played through bars 13-20 -- 19.5% 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 ride, snare and kick, counted in sixteenth notes. On its own it scores 3 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 31 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 104 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 104, 121 and 138 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
