Now doing the NW part again:
7.47 peasants per acre
Raw WPA = 1.70
5 raw TPA
5 Offensive specialist per acre (dragon fodder)
EPA = 13.76
750 BPA
55 NW/A from 100% built land
750/92 + 55 + 7.47 + 1.7*4 + 5*4 + 5*4 + 13.76*5
=
186.22
That's a pretty big drop!
OPNW = .438
DPNW = .236
Total MPNW = .674
So that small drop in mTPA and the switch to TGs and a few o-specs overwhelmed the slight easing back of the DR, and got us .674/.646 = about 4% more military as measured by NW. That .674 is much nicer looking to my eye - I'm a lot more confidant calling that an A/T - the old value was a little on the line. This should, just barely, break the 80% of straight attacker mark, which is a major threshold imo.
