Just realized that we already have 1in the bank, so we don't need to run at 0% tech this turn. I went ahead and switched back to 100%, so we will discover Sailing next turn. Then I will switch to 0% for 1 turn, before switching back to 100% again.
We may want to consider running 100% gold for a few more turns right now. Since we are not ready to build a galley right away anyway - getting sailing a few turns later does not really matter and we will need the gold for our next tech anyway. By doing so other teams that may be teching sailing won't get the tech boost of researching an already discovered tech. Also we don't give away that we have teched sailing until the last possible moment.
Slavery - I know I have bemoaned not switching to slavery a fair amount already and realize that others on the team don't seem to think it is a big deal. But does it not make sense to switch now when Otreta is still working an unimproved tiles? Later on we will lose more production.
