81 bars of 6/4 -- not four -- at 220 BPM, 2:12 of playing on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
44 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
hi-hat through bars 1-9, toms through bars 10-12, hi-hat through bars 13-17, toms through bars 18-19, snare through bars 20-28 and hi-hat through bars 29-33, and 6 more changes after that.
The beat the song is built on is one bar, played through bars 21-27 and 37-43 -- 25.9% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

220 BPM, in 6/4, with the time kept in sixteenth notes. At that speed the sixteenth notes are the whole difficulty, so the room will take it down to a quarter of it and climb back.
44 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it. The beat itself is 36 out of 100; the rest of the number is everything around it.
81 bars, about 2:12 at the written tempo. The course breaks it into 15 exercises over 5 sittings, about 25 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick. That is most of a full kit; the part moves around it rather than sitting in one place.
