Oh, also, a note on how I'm running my calculations. In Excel, I created the matrix of the matches played with each team, took the inverse of it, and multiplied it by the total score vector as was my understanding and as Excel allowed. I have the file here on my thumb drive, so I've uploaded the spreadsheet here.It should be on a sheet named Match Matrix, I believe, though I don't know if the test matrix is in there. There should be vectors in there as well to enter the scores for OPR, the margins, and it should spit out WM and OPR next to them. I think I just used letters to label them, and can't remember using anything really obscure, so they should be easy to identify. If my test matrix isn't there, there will be an empty matrix for match data, and then it'll spit out its inverse next to it or below it. I've done both, and can't be sure which...
If I've done something wrong, it'd most likely be in the math there, I'd think.

Hi,

The data I used was from whatever link to TBA you had in your post so I think it is 2008. I would be glad to take a look at your spreadsheet and see what possibly could be wrong. I can output the matrix and vector from my program and compare to yours. It is getting very late here in Michigan and I need to get up in about 5 hours. I will look at it tomorrow. By the way, I saw that you downloaded my spreadsheet. The program is fixed now so the corrected week two data is available for you to download. Sorry for the inconvenience.
