As I do each age, here are some estimates for "raw" attacking power for the prelim changes. I'll post the redo for the final further down if anything changes. Remember this is just measuring the military for an attacker - there should be other factors going into your choice for race.
A few assumptions have changed - I've pushed the off:def ratio up to 70:30, greater than 2:1. (Had been using 65:35) If it goes any higher you'd be starting in triple tap range of yourself. I'm assuming 90% of max sci on current war, BE and housing, 60% max for the T/M sciences. Given that there is a curve to sci again this probably won't be too hard to achieve. Target pes/a is down to 5, but target mWPA and mTPA is up to 4 apiece. (But good sci means those are somewhere in the 2 raw range depending on race.) All in all, I'm trying to make it more like the age I played orc and less like my strange faery attackers. (Though faery attacker this age is rockin' it... just like I predicted.) Fanat, GP, and the new BL are accounted for, assumed always up (fanat can sometimes play games... and you might run out of runes, but that's your own fault).
So, without any (further) ado, the Age 71 Prelim Power Rankings:
