I played a test from the test save with what I posted and I think it works out quite well.
Wheel and BW are teched on T49 or 17 turns from now (mind you that due to discount differences between test and real game this may vary a turn up or down).
Capital goes warrior-warrior-worker-settler-1 turn of something (other settler I'd propose). Both warriors coincide with growth to size 3 and 4 respectively. 1 warrior covers deer/wheat area in the north, the other the gem area.
Golden Fleece settled on T35, sheep done on T39. Like in the previous SGOTM, it has a nice 2 commerce from being riverside! Neilmeister being an Aussie must want us all to like sheep.
Mine done T44, road done T46. Worker from capital meanwhile has roaded the tile NW of gold and then deer for TR connection on T46. GF-worker goes to mine grass hill SE. Other worker heads back to cap and roads any of the tiles W of the cap, so settler wins a turn moving to gem spot.
Golden Fleece goes warrior-1 turn of warrior to grow to size 3-worker.
Cap finishes settler on T48, it moves, we hit end turn and we get BW. So we still would have time to redirect settler if bronze pops up, otherwise continue to gems. (I'd definitely stop after BW is in). For reference, at this point masonry would take 4 turns, just like PH. With gems online tech would get yet another boost.
I must admit that I continued with masonry and tried for GWall immediately with a settler whip in the cap and a chop, but I got beaten by an AI. Nonetheless it can be built quite quick. However, it won't be a certainty. Likewise, I remember from the test save some weeks back already, that I got beaten to the Oracle in 1560BC. So we shouldn't count firmly on early wonders, though test and live saves might be night and day regarding this. Of course gambling on a wonder with a multiplier in place (GW) never hurts too much regarding fail cash as consolation prize.
Also worth noting I barely had barb trouble in the test save. The lion that we can already see south of gold might be a bit troublesome though if our warrior won't hold against it...
