Filtering Contributors should change the count and the order

Proposal

Currently when you use the convenient "filter" slider on the Contributors page, it updates the graphs of commits, but does not update the total number of commits per user or change the order. For long running projects, I would like to conveniently see who the biggest contributors in the last year or two are, and I can, but the important details are buried. It would make more sense to me if the commits per user changed to reflect the filter period, and the order changed to reflect the users who have contributed the most in that period. Users that have no commits in the period would not show.
