Okay. bcool's test save has HS+Colossus on T123, Glib on T126, using OrgRel. I was able to get HS+Colossus on T122 without OrgReli and I don't want to push our luck. Gandhi's had Theology for a while and once we give Roosy MC, he could theoretically complete forge+Colossus in 5t or even 4t. So I tried about a 1000 times to get HS+Colossus on T122, using OrgRel. And got it finally.
The save below has HS+Colossus on T122 and GLib on T125, using OrgRel. That puts GS in Pigs at 14t, next GP in Moscow at 15t. Without OrgRel I can get T122/T126, but both GPs are then at 15t, Moscow having priority of course. We could 3pop a forge in Pigs some turns later and run an engineer for 4t, thus getting the GP in Fish with a high GS, low GE probability.
The turn of revolt loses us:
18c
56h
28f
The hammers we obviously get back, the commerce probalby also with martket in Moscow sooner and other buildings sooner. The food is hard to measure.
The real question is whether OrgRel continues to pay for the +2cpt and rising civic cost. That may depend on how much free religion spread we get.

bcool, I think you're right about the GS in Pigs.
