And despite how much I complain about how my upper body strength is not improving as fast as I'd like, I'm actually doing multiple reps of the novice one-rep max on the shoulder press these days.

W00t! \o/

I haven't been testing my one rep max in any real sense

I do rec trying it (at a point when you're feeling well-rested and have no niggling injuries) -- it can be quite surprising.

I've been looking at strength standards lately.

I admit I tend to collect them, mainly looking for the ones that make me look good. *g* Gubernatrix has an excellent review of various sets of strength standards (and suggestions for her own standards):
