Assuming that the Peaks in the test game are accurate (they weren't before, which caused us to be unable to easily steal a Worker from Germany), then on:
Turn 23, 3080 BC Our Warrior 1 can attack 1 SE, 1 SE + 1 E, and 1 SE + 1 S of Berlin, with the Berlin square being visible
Turn 24, 3040 BC Warrior 1 can attack 2 S of Berlin without seeing what's in Berlin (but we would have just seen what's in there on the turn prior)
Turn 24, 3000 BC Warrior 1 can attack 1 SW + 1 S of Berlin without seeing what's in Berlin
In our test game, a German Worker appeared 2 S of Berlin on Turn 27, 2920 BC, but when and where a Worker may appear will be subject to the terrain and Resources of the real game.
Assuming that the Green AI isn't blocked off by Peaks and assuming that there's a square from which we could steal a Worker, and assuming that the Green AI's capital is roughly placed correctly in the test game, then on:
Turn 28, 2880 BC Warrior 2 can enter Green AI's Cultural Borders in the test game
We may or may not end up sending out Warrior 2--Paris can grow to Size 5 without a Military Police Unit and remain Happy. Paris can grow to Size 7 with a Military Police Unit and remain Happy. If we're going to build a Library in Paris, then we'll need a Military Police Unit as of:
Turn 40, 2400 BC (that's if we Camp the Deer before Camping the second Fur)
So, we actually have just over 10 turns to play with potentially trying to steal a Worker from the Green AI and getting our butts back to Paris.
For the case where we Camp the Deer and complete Settler 2 on Turn 31, we will have 85 / 90 Hammers in a Library on Turn 45, 2200 BC, with 8 extra Hammers coming in on that turn, meaning that we can hire Scientists starting on Turn 46.
What's surprising is that if we delay Settler 2 by 1 turn in order to dump overflow Hammers into the Library on Turn 32, on Turn 45, 2200 BC, we will only have 84 / 90 Hammers in a Library. I'm not sure what happened there, but basically, I didn't find a way to speed up the completion of our Library, so we should probably stick with the Turn 31 Settler 2 for the Writing -> Fishing -> Alphabet approach.
Now, how about what to do with Worker 1 after Pasturing?
Let's say that we ignore Camping the Deer initially.
Turn 28, 2880 BC Writing -> Fishing
Turn 28, 2880 BC Worker 1 pFarms at 1 N of Paris
Turn 29, 2840 BC Worker 1 moves to the G Riv For that is 1 SE of Paris
Turn 30, 2800 BC Worker 1 Roads the G Riv For that is 1 SE of Paris
Turn 30, 2800 BC Paris works Unimproved Deer instead of the Fur to complete Settler 2 one turn sooner
Turn 31, 2760 BC Paris builds Settler 2 -> Library
Turn 31, 2760 BC Paris works Fur instead of Deer
Turn 31, 2760 BC Before Settler 2 moves, Worker 1 completes the Road, saving Settler 2 a turn of movement (it's as though we built the Settler on Turn 30 for the south-east location)
Turn 32, 2720 BC Worker 1 moves to the second Fur
Turn 32, 2720 BC Orleans gets founded, but we are 3 Flasks short on learning Fishing, sigh
So, I put 2 Hammers into a Library before building a Work Boat. After Camping the second Fur, I built a Road 2 SE of Paris and then Camped the Deer.
Turn 41, 2360 BC Paris grew to Size 6 one turn later
Turn 46, 2160 BC City 2's Work Boat was built
Turn 46, 2160 BC Paris is short by 3 Hammers for completing its Library
Turn 50, 2000 BC We only had 432 / 448 Flasks in Alphabet, meaning a Turn 51, 1960 BC Learn Alphabet
So, Alphabet didn't come any sooner and our Library came a turn later.
Okay, what about if we don't speed up Settler 2's movement but we instead set up a Trade Route network before City 2 gets founded, so that City 2 immediately is connected, giving us 2 Trade Routes on the turn that City 2 gets founded, then improve the second Fur as soon as City 2 gets founded?
Turn 28, 2880 BC Writing -> Fishing
Turn 28, 2880 BC Worker 1 moves to the G Riv Deer For
Turn 29, 2840 BC Worker 1 moves 1 SE and does something at 1 SE + 1 E of Paris, probably a pFarm
Turn 30, 2800 BC Worker 1 moves 1 S G Riv (2 SE of Paris) and Roads
Turn 30, 2800 BC Paris works Unimproved Deer instead of the Fur to complete Settler 2 one turn sooner
Turn 31, 2760 BC Paris builds Settler 2 -> Library
Turn 31, 2760 BC Paris works Fur instead of Deer
Turn 32, 2720 BC Worker 1 moves 1 S to the G Fur For
Turn 33, 2680 BC Orleans gets founded on the turn when we learn Fishing and we immediately have our Trade Route connection
Turn 33, 2680 BC Worker 1 starts Camping the G Fur For
Turn 36, 2560 BC The second Fur has been Camped
Turn 37, 2520 BC Worker 1 moves 1 N to the G Riv (2 SE of Paris) and pFarms
Turn 38, 2480 BC Worker 1 moves to the G Riv Deer For
Turn 42, 2320 BC The G Riv Deer For has been Camped
Turn 46, 2160 BC City 2's Work Boat was built
Turn 46, 2160 BC With 2 turns worth of microing a G For into a G Riv to avoid fractional Flasks and fractional Gold (two different turns at 50% Science--we might have also just done 1 turn of 0% Science), we have 85 / 90 Hammers in a Library
Turn 47, 2120 BC Paris' Library has been completed and we hire 2 Scientist Specialists
Turn 49, 2040 BC We have 410 / 448 Flasks in Alphabet and will learn it in 1 turn!
So, we end up with Turn 50, 2000 BC Alphabet with barely any overflow Flasks (maybe 1?) and 6 Gold in the bank
Paris is Size 8 and Unhappy, but we've been building Settler 3 from that turn that we grew to Size 8, so we don't care that it's Unhappy (the Unhappy citizen does not eat 2 Food when building a Worker or a Settler).
We have 41 Hammers in Settler 3, which means it will be 5 turns to complete it... but, after 2 rounds of trading, 1 turn of Anarchy, and 1 turn to whip (on Turn 52), we will actually get our Settler 3 three turns later, on Turn 53, giving us 31 Hammers going into a Granary on Turn 54, meaning that we can 1-pop-whip our Granary at the ideal time without needing to wait for a Forest Chop, while still having a Size-5 Paris.
I'll have to play through it again to make sure to document the micro details, but Turn 50, 2000 BC Alphabet with us already working on generating our first Great Scientist sounds pretty solid.
Thanks for the comparison data, Jersey Joe!
Turn 50, 2000 BC:
Paris is Size 8
4 Food
41 Hammers in a Settler
18 GPP in our first Great Scientist (14 turns to go at 6 GPP / turn... probably more like 15 or 16 more turns if we Whip a Granary in Paris)
We just learned Alphabet (should be Turn 50 Pottery and Turn 51 Bronze Working)
Orleans is Size 2 (Size 3 in 1 turn)
22 / 24 Food
8 Hammers in a Library
Fish netted
(Ignore the signs in the screenshot, as I did other Worker actions in this test run. I also World-Built myself a Military Police Swordsman as I didn't time the arrival of Warrior 2 back inside of Paris properly.)
T40 2400BC Bronze working learned started Pottery (revolted into slavery)
T45 2240BC Pottery learned started Writing
...
Orleans is size 4 and can whip a granary
If our Worker isn't doing all of the extra Worker actions that it did, such as building Farms and a Road on the south-east Fur (a Road on the south-east Fur is only needed if we get a Trade Network connection to an AI for Resource-trading purposes, which means learning Sailing or building a Road to an AI), we could probably put a Chop into that Granary and combine it 3 turns of making 4 Hammers per turn to be able to 1-pop-whip the Granary on Turn 48, if doing so is more efficient Food-wise.
Did you build yourself Worker 2? I made do with only one Worker, but that fact means that we're short 60 Hammers worth of production, which is another comparison factor. If we stole a Worker in an Alphabet-beeline approach, there might not be much for him to do until after we learn Alphabet, but then there'd be a lot to do riht after learning Alphabet (Forest Chops, Cottages, building Roads to new Cities for Whipped Settlers, etc).
