That book report sticking looks like a flam paradiddle to me, unless I'm reading how you wrote it incorrectly. Unless there's some mistake, a book report is:
RR l (l)r rr LL r (r)l ll, where RR and LL are accented diddles, rr and ll are unaccented, and (l)r is a flam.
If something has more than one name, just choose one and use that. Since when is Bachman infallible?
It doesn't even really matter anyway, I've seen eggbeaters written as straight fives and as three sixteenths plus two thirtyseconds...like the first half of a sixlet plus a diddle. Just learn everything with proper accuracy and technique, play it off the left, invert it, play it inverted off the left, move the accent to every beat of the rudiment, and you'll be set for corps and PIW.
