There is a correlation between good and poor scorers when considering the entire list, but the error in the ranking is as high as the number of alliances for the finals.

You would not want to use the power rating to do any picking if you are lucky enough to be picking in the nationals. Neither would you want to be using your own scoring from prior regionals as significant changes in performance can occur. You need to field a scoring team for your divison at the nationals. Doing a good job of that will serve you well...

Those are some interesting statistics. So how did these rankings factor in while picking alliance partners for your team? Especially where 1569 fit in as a first round draft pick.

Also which matches does this data include? as far as practice, qualifying, and elimination matches.

Thanks!
