[QUOTE="orientalnc, post: 449196, member: 1199"] Years ago I tried building a metric based ranking system. I had all the mainframe power I needed in our Bell Labs center. My bosses were even OK'd the project because I was using the new UNIX based DB called Ingres. But, no matter how much we tried, we could not remove the subjective aspects of the algorithm completely. Every ranking system has to have a starting point and it takes a while for those decisions to weed themselves out of the model. Inevitably, you have to accept that someone(s) will be looking at team A and saying they are better than team B. This is very similar to a football ref following a play where the ball carrier is tackled 25 yards away. He races across the field and puts his toe where he thinks the runner first touched the ground. Then the chains are brought in to determine and the spot can be a half inch short or beyond the stick. That is a very precise metric for a very imprecise event. If we beat Duke by 8 points at home is that better than UNC beating Duke by 1 in Durham? I am sure the model will say it knows, but is that really correct? [/QUOTE]
