Yeah bc it's not weighed as results-based against caliber of opponent. Which in sports is funny bc that's the point, lol. The NET was supposed to do more of that with the mysterious formula, quads, etc.
But KP has great value to assess teams aggregate level of play and strengths/weaknesses at a given point in time. But you have to dig into the trends. It's a better scouting tool than trying to rank teams on a profile which should be based on actual results. That's why even Ken Pomeroy himself basically tells people to use it that way and not as the be-all, end-all to evaluate a team's NCAA Tournament profile.
