So, assuming RB did go into Revolt last turn, that would push back their completion date to T51. If they needed to save gold for one turn, that could push it back further to T52. They are ahead of us in Turn Order, so they win in the event of a tie. Also, keep in mind that these are estimates, I could be off here.
Right now, we could get Poly by T50 if we don't switch to Hunting (or T51 if we already switched off last turn, which is possible). However, this would guarantee that Terasvin is the Holy City. Personally, I'm less than enthusiastic about Terasvin as a Holy City, so I say stick with the plan and hope for Judaism in a good location if we miss out on Hinduism.
