Duckweed, I am not sure what you mean re. Axe movement. The western Axe captured a Worker and then severed the road 1S of Constantinople. As you can see from
my posts, this process was slowed to T40 by Asoka's Archer movement, and on T41 I chose to revert to the Grassland hill. Nobody had suggested moving the Axeman westwards, and I opted to continue harassment (as you yourself had suggested).
The Southern Axe farmed XP and then remained in place to heal. I was unable to move it further away due to the barbarian Axeman threatening the Settler, which will attack units outside of borders. I suppose I could have moved him 1W on T41, if that is what you mean.

I attach one last save for comparison. I delayed the Academy by one turn, so I imagine that the

looks weaker. The capital produces 38.5

with the slider at 100%, but only 22

at 0%.
Although comparisons are difficult, especially because you are building Wealth in your save, here are some pictures:
I'm not certain what we should do about the building wealth thing. Me and Soundjata wants to turn hammers to wealth while you want more axes and perhaps started libraries. Without anyone else mentioning their stand I will go with building wealth. As for comparison we can just add up hammer with gold.
I not sure about whipping a Settler in the capital to speed up city #5, but perhaps you can find a way to make it work?
Settling Amsterdam on T51 gains a four turn head-start versus slow-building the Settler (T55) in the capital. This gains four turns of production (let's say +20F) with four turns of additional maintenance (-16C). The whip also means that we can work one less tile in the capital for 10 turns, and population here is valuable, especially when we are running Scientists (Corn/Pigs/Copper/Marble/Riverside Cottage/2x Scientists = 7-pop to work good tiles). Settling sooner also means that Workers are needed further north sooner, so improvements in our current empire suffer in turn.
Let's say 14 food and 13 hammers. I would say is worth the upkeep of 16C, if we decide to chop we get 12 food and 16 hammers more. I'm unable to determine the exact cost for the capital from work.
The matter is not clear to me, so I leave it up to you. Being able to whip a Granary at size 3 (with 31/60H) and preserve a forest would be one good argument.
I think the forest in unrelated. It will always be possible if two workers are ready when we settle the city.
As soon as you post a final PPP I will give a thumbs up or thumbs down.
