For labour production I find it better to use le mans and nantes. ie the 2 textile provinces who suck at producing luxuries and spice.
Start building 2 roads in le mans and 3 roads in nantes allocate full labour to develoment. That increases max pop by one.
Then focus le mans on building factories to 10 and nantes on building docks to 10.
Than le mans starts building barracks to 10 and nantes starts building factories to 10 than barracks to 10.
Then you can shift labour allocation from development to labour production. Your shooting for high labour production with max morale production of cav, arty, inf and ships. The level 10 factories max arty morale and speed up unit production and produce labour.
Never thought about that, will have a look at it next turn, however building lvl 10 factories is likely going to force me to save up labour over atleast 3 or 4 turns a piece...
