How many dark greens equals a blue?

[formallydickman]

My understanding is that if you are killing a BLUE 35 it will yield something like 91,875 xp, while a GREEN 34 will yield 86,700 x 50% penalty = 43,350 per kill so you'd need 2.12 green 34's to = 1 blue 35.

I'm not sure this is actually correct, but it seems to match with what I casually see in game.
