I spent about two minutes to copy, paste and run the macro. I didn't really look at the numbers. Since the total OPR number matches what somebody else posted, I assume the subset OPR are correct also.

It's definitely a case of the sample size effect. OPR can produce some very funny results when restricted to a limited range of values over a small array of matches with a large array of teams.
