hey ilios, nice plans 
i went and had a proper look at how tech works + posted earlier in the thread
i think we come out ahead by taking AH first rather than mining+BW, but not by much. up to you guys.
i went and had a proper look at how tech works + posted earlier in the threadQuote:ok guys given all the debate (read: on my behalf) + the fact we SHOULD damn be able to put together a good micro plan with all the time we have i've finally had a serious look + understood the tech mechanics

what it means is, for example, for AH we know both optional techs, which gives us a 40% bonus to beakers applied to the tech. the base beakers are (whatever your total beakers are + 1)
say we're pulling 10 beakers/turn. for AH our beakers applied to it per turn once we get Ag would be (10+1) * (1.4) = 15/turn, so AH would take 12 turns
mining would be full cost but BW as ilios pointed out would only take 17 turns at 10 raw beakers output.
