When you first load the page, using your link the first column is "Rk" which stands for rank. The glossary helpfully explains that but doesn't say what it's based on. I figured it out that it is sorted by the SRS column.
Phil, when you first open up the SRCBB table it appears to be sorted/ranked by SRS, which is their proprietary ranking system.
If you sort by any of the other columns, the teams will be ranked by that sort.
While immediately conceding it isn't clear how to determine whether net rating or SRS or AP or Massey or anything else is the best without some clearly defined acceptable metric, do you know if anyone has done regression of any of these measures against end of season AP ranking?
Yes, there are many computer rankings, mostly using proprietary algorithms and regression analyses of various kinds. And then there are human polls. It's anyone's choice as to which to believe is the best.
The only comparison of all these ranking sites that I'm aware of is the Fun Bracket that pilight from RebKell would enter the NCAAT pool. He'd enter brackets for the final rankings in the AP poll, Coaches Poll, NET, RPI, Massey, Warren Nolan, and a bunch of the other computerized ranking sites. He'd end up with a ranked list of how each human/computer ranking site did in the empirical competition of the actual NCAAT.
He did this for decades, but RebKell is now dead, so his threads on the Fun Bracket pools are gone. In different years, I recall Sagarin and Massey each won it two or three times. In recent years I seem to recall AP and RPI winning. I suppose pilight could be contacted to get all the historical results. His website (can't link it for some reason)—search on his name plus dot x y z)—doesn't have the Fun Bracket results, but does have an email address for him.
