Excellent then. Where should the workers end up for Deity's last turn according to that test+actions?
Here is the worker micro around Silk+Fish in my latest test :
-T69 : The worker who just finished the PH NW of Wash (named Worker 5 in the test game, thereafter W5) moves to the PH SE of the silks.
-T70 : W5 moves on the southern Silk
-T71 : W5 chops and cancel
-T72 : W5 moves on northern Silk || one of the worker who just finished roading the gold (Worker 2 in the test game, thereafter W2) moves 1N of the Wash sheep
-T73 : W5 chops || W2 moves to the forested grass hill 1SE of W5
-T74 : Silk+Fish settled || W2 chops
-T75 : W5 chops into a WB
-T76 : WB moves on fish || W5 moves back to southern silk || W2 chops into granary
-T77 : Border pop => work improved fish || W5 chops (2/3) || W2 moves to pigs and pasture (1/4)
-T78 : W5 chops into granary || W2 pasture (2/4)
-T79 : W5 moves to pigs and pasture with W2 (4/4) || City works improved pigs || the granary is up while Silk is (10/22) so it will be full when growing to P2
-T80 : W2 and W5 move to forest 2E
-T81 : W2 and W5 chop (2/3) || City grows to P2 (14/24) => work improved fish
-T82 : W2 chops into WB || W5 is free to go somewhere else
-T83 : City grows to P3 (17/26) => works unimproved FP || W2 is free to go somewhere else
-T84 : City grows to P4 (14/28) => works food neutral tile
-T85 : Clams improved => City works Pigs+Fish+Clams+FP
...
-T91 : City grows to P8 (34/36)
I think it's pretty optimal, but you can always correct it if you find something better.
