I think the but is actually spelled butt. As in, reading the last chapter (ass end) of a book with a bad ending.

If there's any other hard math people are curious about, I have basically all of it back ended to reverse engineer the game aside from the PCI growth formula, which no one even in LaF was smart enough to figure out, and that developers have for years dodged me on. I have the e2025 one tho, so it's not here nor there. Sad today about people leaving.
