Accidentally rederived Lanchester's Square Law again, in a different way than I'd seen before. If your units are X times as good as mine and each of your units hits p of the time and mine q, then each of your units should take out X times as much stuff as each of my units. You unit takes out p*1 of mine, and mine takes out q*1 of yours, and yours are X mine, so mine takes out q*X my-units of yours. But yours are X times better so we'd better have p*1 = X * (q*X) or X = sqrt(p/q). You'll need 100/X to tie my 100.
A coworker mentioned a Jeff Atwood post that points to Luke pointing to Richard Wiseman. Yessssss.
I traded off going to my favorite restaurant for everyone else having a better chance of not having bad service there (Friday). Definitely the kind of trade I want others to make, so I made it.
I wrote up most of the stuff Anna asked for in her "retrospective please!" mail, but it's not quite done. I'll finish tomorrow.
