I use Flotte's guide. Then change all houses with villas and every 2 tailors with a goat farm, slowly.
You need 5 arches for the villas, so an additional expansion.
This is the map I aim for (+ one expansion with 5th Arch!)
View attachment 11273
The 10 villas bring the hourly action points to 7000 (= two action with no movement).
Keep in mind that you recover the lost action for substituting a cottage with a villa in the next 10 hours.
You recover the supply production of 2 destroyed Tailor with a Goat farm in 2 production (1.33 to be exact).
The expansion with the bold border (and 2 arch in it) can be located anywhere. Same for the 5th expansion not in the map. But the first 3 need to be adjacent for Flotte's plan, so you need to clear obstacle if you are unlucky.
But you can use mirror images of the map to never have to clear more than 2 obstacle (and in most cases up to just one).
It would be helpful if the coin and supply info boxes contained the total coin and supply production of the settlement in the next 10 hours (so without any building currently under construction).
