By T32, York has been settled (alas, no seafood) and the next worker appears. He rushes over to help his buddy. Pottery is still 8 turns away as my research slider drops to 70% with the new city. I'll do the 0/100% thing to squeeze out as much research as I can.
At 70%, I get 0
and +8
.
At 0% I get 9
and 0
At 100% I get -3
and +12
So at 70% over 4 turns I get 32
At 1 turn of 0% and 3 turns of 100%, I get 36
Both leave me with a total of 0
Now I can see how this works!
At T36, I find de Gaulle is my neighbour to the east. He's just settled a city quite close to me. Now, he could be a good first target for war. Paris is often stuffed with wonders. My workers are finishing the rice farm. I want to get those London FPs cottaged as soon as possible, so I think I'll send one over to do that while the other mines the copper. York and London are both two turns from a pop increase.
