The problem there is that only 2 or 3 IC players actually have comparable tournament results. We can't compare Hozart's record to Azn_Lep's because they never play the same people. Trying to draw conclusions from their tournament records would mean assigning values to the people they beat, which is clearly a hopeless situation. The national power rankings committee could scarcely do it for the top 25 people in the nation, a group that travels all the time and has hundreds of matchups against each other. How would you propose we do the same when only 1 IC player travels nationally, and another 2 or 3 travel strictly within their region?
