The Vance pattern wasn't rocket surgery...
In the big scheme of things it doesn't sound much harder to wrap your brain around than CV, LHA/LHD, or "air capable ship" patterns, go figure... and when you take the Navy Primary pattern and add the delta pattern (which you might actually do), PPEL(P), all the other alphabet soup, Whiting split field ops, then it's not exactly simple either.
I realize all that is small consolation to the stud pulling his hair out trying to memorize that stuff, but like you said it's really not rocket surgery.
