4,22,33 is an odd-metered pattern for inserting various hybrid rudiments, much like Mission or the 5/8 and 7/8 chuggadas. It's a fun chop-out exercise, and there are plenty of variations to keep you busy. I think it's a little more groovy than the chuggada exercises, and there's a lot of growth to be had in working on the different flam-tap and invert variations with both full accents and slight accents.

Gonna take this to my instructor and get the snareline playing it all season.
