I counted 49 internals/barbs for nMe., which with his average village points, equates to 397194 which is roughly 35% of his points.
Soi6, has 18 internals/barbs, which with his average points, is 153522 which is 16% of his points.
Illuminaz has 46 internals/barbs, which with his average points, is 383364 which is 42% of his points.
Killer Willard has 45 internals/barbs, which with his average points is 360315 which is near to 43% of his points.
Cryptic Codex has 16 internals/barbs, which with his average points is 137376 which is 17% of his points.
In comparison to the rest of the top 5 only 2 players have received less of their points from internals/barbs than nMe. one being in Infect and the other in Dsy4. I couldn't be bothered to do more than the top 5, so as mattcurr said others in the top 20 may have a higher percentage, but in terms of the top 5 it's 50/50.
I should note that I used average village points when calculating how many points came from barbs/internals, so it wont be completely accurate.
