You're discounting the effect of the age factor -- I don't downvote high-position low-score comments for reordering purposes because I know it'll probably decay down anyway. I don't want to be the asshat to drop a comment below 1, just because there's a better comment that's currently below it (but probably with more karma). At least from my usage, you'll see a net gain in karma inflation.
