Hi,

I looked at your spreadsheet Suffield Shakedown Test.xls. I think you assembled your matrix A incorrectly. For example, the diagonal terms represents the number of matches each team played. They should all be 4. Team 126 and Team 181 did not play 9 matches. Also Team 40 never played with Team 173 so that term should be 0 but you have a 2 there. You must have entered the numbers wrong by hand.

I am attaching the matrix A and vector B. You can try it out and see if you get the same OPR number.

I also looked at your spreadsheet Scout_System_beta_v.5.xls. Even though I am already posting a similar one for everyone to us, I would strongly encourage you to continue to develop yours and customize it for your team. You will learn a lot from doing it. If you need any help or have any questions, just let me know and I will do my best to help.

Regards,

Ed Law
