Rankings

Metrics span many orders of magnitude, so the radars show ranks, not values. Two rankings per metric: the best result to date, and the pace of improvement fitted on recent results. Drag the year slider to replay history.

Pace is the slope of a least-squares fit of log10(value) against year over the chosen window, the same fit as the dotted lines on the home page. Platforms without a result on a metric are left at rank 0 (the center).
