Doesn't work that way...
[EDIT: Actually it's similar, but not the way you think, because you almost NEVER get all 3 teams evenly fighting each other, almost always the weaker team is ganged up upon, and often times that's the knits]
If there's 10 players on, knits have 25%, that's 2-3 players. If there's 100 players on, knits have only 25 (against a combined 75). Much worse. Assume there's 300 on, then there's only 75 knits against 225 enemies.
Percentages get WORSE (in effect) the larger the number is. Especially as enemy density per sector increases.
