Heh, that was a shifty way of introducing an application site, snawdog. =P
I think most alliances these days have strats and formulae posted for their members (I know LCN certainly does!), but the eewiki has a few of the basics (although it's certainly not comprehensive).
http://www.eestats.com/techcalc is a good resource for calculating tech %s, and it has the maxes on that link. bus/res is 180, but with the tech rate formula being modified recently, tech is more numerous; I'd say the ROI balances out at about 167-168, depending on how early you get it in the set (and which server).
3 turns for 12 hours, 6 for 18. Don't forget to use the bonuses, too. They're a lot different in this new game, but definitely useful (especially if you're running a casher).
Oh, and in case you do want to find your way back to LCN, we're at
http://lcn.boxcarhosting.com these days. =)
