Bias: a partiality that prevents objective consideration of an issue or situation
The fact that a group of humans came up with the criteria doesn't alone make it bias. I don't have an intimate knowledge of the formulas used in any of the 6 computer rankings, but would assume "someone in the know" gave them the thumbs up.
I think the system works pretty well, but I would weight the computer ranking higher. 8/16 team playoffs would be bring in a lot of cash, but splitting the pie would be a big issue to overcome.
