Attached are screen shots of our cities as they are currently configured. This configuration is what I looked at in developing the current PPP. I think it is a bit unfair to criticize the PPP based on reconfigured cities which I hadn't seen until I checked the Team Thread this morning.
That being said, I don't have a problem reassigning the citizens in any city, if the Team decides that the way we should go. However, it should be pointed out that we are currently running 0% Science and only generating +2

/turn, so the only

we are generating are coming from the Scientists currently being employed. Reassigning those Scientists to work Mines or Cottages will pretty much shuts down our progress on any research.
Therefore, I think we need more consensus on how much research we want to sacrifice for short term production before I revise the PPP.
Additional comments...
Workers: we have 4 Workers for our 6 cities, so IMO, Yes, we need more workers.
Paris: no matter if it employs 2 Scientists or works 2 more Plains Hill Mines, it is still at stagnant growth
and at it's happy cap. Additional tile improvements in Paris' BFC are a waste of Worker Turns without a Temple to raise the happy cap so that the newly improved tiles could be worked, and a Temple only raises the Happy Cap by 1.
Spy whipping in Paris:
as currently configured, adding a Spy to the build queue indicates 4 turns to build, or a 2-pop whip with 20

overflow. Paris is
currently generating 10

/turn, so I think we could build the Spy for 1 turn and still 2-pop whip it, generating 30

overflow. (Others here are much better than I on calculating whip overflow, so please check me on this) Reassigning the 2 Scientists to PH Mines builds the Spy in 2 turns. I don't see a way to get the Spy out in 1 turn. Again, I can do it either way with team consensus. Perhaps we should go the 2-pop route and put the overflow into a Worker?
Orleans: 5

are invested in the current 50

Barracks build. Building Research here and in other cities is just a stop-gap measure to supplement our pitiful research rate while we heads toward Currency or some other tech.
Lyons: could reassign the 2 scientists to PH Mine & forested PH, and complete the Chariot & Forge in 2 & 3 turns respectively, at a cost of 7.50

/turn. Or could reassign a Cottage to the riverside PH Mine and complete the Chariot & Forge in 3 & 5 turns respectively, keeping the 7.50

/turn but losing 2

/turn, which would make our Treasury have Zero income. Or we could try R1's plan of 2-pop whipping a Barracks. We have 13

invested in the 30

Chariot build, and are losing 1 hammer/turn if we don't move it up in the build queue. Not sure how many turns we would have to build a Barracks before getting a decent overflow from whipping. How much do we care about losing hammers on the Chariot build?
Tours: the 1-pop whip of Spy was based on the theory that we wanted to get 2 Spies down to Brennus ASAP. If we don't want to whip here, might be better just to build 2 spies in Paris.
Brennus has 1 Buddhist Missionary near us, he is currently 3E of Tours. Not sure if he is heading toward Rheims or Marseilles.
