I think we should still start with Education, hoping to go into Liberalism. Whoever we meet, we'll put full EPs on (weight 1 in case we meet others) and hopefully we can see their research sooner or later. If they get ahead of us on Liberalism, we can just abandon it, but Education is still very important because we'll want to maximize our beakers with Universities anyway.
After Education, we can do Astronomy for the Observatories.
As for turn sets, there are no rules for the SGOTM, right? I didn't see any, even after I read the rules more thoroughly. I think 10-turn bits is OK for now. If it gets closer to the game's deadline, we can up the ante, but I think if we each do shortish sets, spend a half a day talking, and have quick turnover on the sets, we should do alright.
Whatever we do, I don't think we should get bogged down worrying or debating every possibility. We're still here just to have fun. After all, we named our team in expectations of our results. (Still, maybe we can do better than that.)
