The beat the song is built on is one bar, played through bars 5-19, 21-36 and 39-46, and 3 more places -- 86.8% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 11 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 29 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 80 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 80, 93 and 106 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
