Sorry, I didn't realize you were adding the elimination matches also. That explains why some teams had more than 4 matches. Can you try doing it with qualifying matches only and see if you get the same results as mine? You probably would. I think there were quite a bit of discussions a year ago about whether to include elimination matches into calculating OPR and the consensus on CD is not to include them. The reason is it will bias the results because some teams will have a lot more matches than others. I need to come up with a better explanation when I have time.
