Seasonal Churn

With just a couple of weeks to go until testing begins for the 2015 F1 season, I thought I'd have a quick look at how the championship standings have churned over the years (eg Calculating Churn in Seasonal Leagues).

The churn value shows how different the league standings were to the previous year: a low churn (or adjusted churn - a volume normalised to the range 0..1) suggests little change that may be indicative of low levels of competitive change on a year on year basis.
