In deference to the importance of the second largest grouping of Roller Derby leagues, representing the entirety of Men’s Derby in Europe, we also present the ranking for that group. (Of course, no absolute comparisons between this ranking and the above are possible, as no bouts have taken place between the two in the past year).

Of course, as the Flat Track Stats dataset contains the entire history of (revival) Roller Derby, we can compute historical data using our ranking too. We ran 60 hours of calculation generating historical rankings for the past 8 years, to show how the community has evolved over time. As our ranking is normalised, the best team is always at 1, and the worst near 0 – in order to show how absolute performance has changed, we also show the underlying, non-normalised, rankings below.
As should be clear, the “peak ability” in Roller Derby increases fairly reliably year on year. As new teams enter the ranking mostly near the bottom, we believe that most of this increase in peak ability is actually due to the top teams getting better (as this is a relative ranking, it would also be possible for everyone else to be getting worse). We estimate, then, that (relative to the worst, “just starting out” leagues), the WFTDA/MRDA Top 10 leagues have increased their effective ability by a factor of 49!† (from the Score Ratio metric).
On the next page, we’ll compare our results to what WFTDA and Flat Track Stats have.
*We’re working on a refinement, to be added in our next table update, to allow “ghost” rankings representative of leagues who drop out of the connected group between ranking calculation periods.
