It’s the basic Least Squares method Wayne Winston refers to in his book Mathletics (which has been referred to on here on a couple of occasions). Basically I do that system as I can’t get the SRS to work properly (I got the Massey system Neil referred to in a post a couple of weeks ago working today – haven’t factored in home advantage or capping in it yet and have slightly off numbers at the moment but I have an offense/defense and overall rating). The disadvantage of the Least Squares system is that the easiest way to run it is using Solver in Microsoft Excel but the variable limit within the Solver essentially means you can’t use it for College Football practically (limit of 200 variables).

George,

What is the Least Squares method?
