75 bars, 4:50, at 62 BPM: slow enough that every note is exposed. Crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot and nothing else.
74 out of 100: demanding, mostly on the independence between the hands and the feet.
hi-hat through bars 1-43, snare through bars 44-46, hi-hat through bars 47-48, ride through bars 49-52, toms through bars 53-57 and hi-hat through bars 58-67, and 3 more changes after that.
The beat the song is built on is a 2-bar phrase, played through bars 13-19, 34-40 and 58-60, and 1 more place -- 26.7% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It cuts the song into 25 exercises -- the grooves, the fills, and the joins between sections, which is where players actually come off -- and puts them in the order a teacher would. Each one opens on a reduction you can already play and adds the notes back a rung at a time, with a tempo to reach and a gate to pass before the next.
62 BPM, in 4/4, with the time kept in thirty-second notes. Slow enough to hear every mistake, which is why the room lets you sit at the written tempo rather than under it.
74 out of 100: demanding, mostly on the independence between the hands and the feet. The beat itself is 52 out of 100; the rest of the number is everything around it.
75 bars, about 4:50 at the written tempo. The course breaks it into 25 exercises over 10 sittings, about 22 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.
