problem is, if 9 turns regrow cycle is correct, after 3 settlers we down to 4 max pop.
I would advise to play test game, in one whip settler - overflow to mids, using second city to produce workers, in other do what ever you think best.
Add couple bureaucratic chops into mids and see how mach mids happiness helps to continue cycle and support city after we finish expand
There no interference between exploration and mids.
I do not want to run tests again
I did damage already :0
Reseach wize I see :
Massonry:- fishing-saling:AH
We do not want to waster turns to connect cities and we want to benefir from trade and start BW atright away.
worker turn after connecting stone could be used for exploration WB and/or chop to mids befor AH ready.
