See ! While my post was primarily tongue-in-cheek (I hope people realized that at least at the Gross Community Product mention ), the bottom line is that different areas of the community are developing/changing at different paces, which will invariably lead to karma disrepancy after a while, even if we get the formulas right initially. Also, as we progress, sqrt will serve us less and less - because it will become clear even without looking that the high scorers will be those that are active in an area that is non-sqrt influenced.
