Thank you, Red Fireball!!! for taking over stewardship of this project's findings summary in the OP! It looks great, and I'm so glad to see people stayed curious and kept hunting.
irl issues have kept me from getting back into GW (or guru, an essential part of "into GW" the way I played) for many years now. Stuey tracked me down elsewhere and left me a message about Guru is closing (which it still took me weeks to find and read, grrr @ irl issues!) Luckily it's still running several days after the cutoff when I get back to look around. So glad to get a chance to express my thanks here!
