Latest version, taking the sheep into the picture:

In this scenario we leave the game tile unchopped, instead chopping the forest tile next to it. Benefits over the previous one are an extra curragh or warrior (which could possibly be traded for a one-turn speed up on the first two settlers, no effect in the long run), the second worker comes online one turn faster, and the settler pump is running at 3.5->5.5 which means even lower luxury rate.
One thing worth noting: It is possible to run Smurkzdon as a 5-turn combo factory producing 2 warriors and a settler, or some 20-shield unit plus a settler, at 5.0->7.0. We are one shield short of running a 4-turn warrior-settler combo.
Also noteworthy is that once the settler pump is running, the game tile is all but unused (except to provide the +2s on growth which a mined hills could do instead). This means we could give it to a secondary town, possibly chopping it for faster growth there. We could also chop it, irrigate it and use it in the pump, letting the sheep go to some other town. However, if we want to run the 2-warrior combo factory later on we need it with the forest intact (for a single 20-shield unit we don't).
If I hear nothing in the next 30 mins or so, I'll keep playing after this schema.
EDIT: Crosspost with zyxy. The granary can't handle 7.5, it doesn't exactly empty but you need more to fill it up.
EDIT2: Oh, and the last two lines are just to show that we can easily have a 2-turn worker pump if we like.
EDIT3: Changed the spread sheet to a correct one.
