Ummm.... here's your own numbers, back atcha.
Karma 100% (By your estimation): 271,252,158 NS: 47,043 nukes
Karma 50%: 135,626,079: 23,521.5 nukes
Hegemony MAX With Coalition of Cowardice (CoC): 79,971,536: 13,197 nukes
I sincerely doubt Karma would ever have reached that 100% mark, but they would not be as low as the 50% (which you labeled MAX on your spreadsheet in the final analysis). Also, the nukes will likely be more than halfway between the two numbers, as micro-alliances wouldn't have access to them.
I'll give you the average NS point, but that is all. Even with 50% strength, Karma would almost double the nukes of the Hegemony. With only 15 million more overall NS, Karma would double Hegemony in that category as well. And 15 million is small potatoes when you're talking the entire game.
The CoC is aptly named.
