If you say the Doom fishing pond is the Top 300, which is 203K NS and up then:
Oculus and RFI make up 68% of that tier, add us and alliances immediately tied to Oculus or RFI then that's 88% of the tier.
If you take out those nations in perma-peace-mode then you're left with 26 nations inside the Top 300. Of those some will be in alliances we've raided, some we've raided and decided not to raid again, or some we're yet to raid - you can't overfish the pond!
