Introduction
Every once in a while I check the UK Art de la Guerre (ADLG) ranking provided by the British Historical Games Society (BHGS). Not least because I find them statistically quite intriguing if somewhat strange. This week I decided to dig a little deeper and do more than just note my latest ranking.
How the rankings work
They are convoluted and closer to an algorithm than commutative arithmetic:
- Players receive points based on where they finish not on the result of individual games.
- The points available differ by event: larger competitions offer more points.
- The rankings only contain the results of events in the previous twelve months.
- All results are included until the seventh event and beyond, when only the player's six best scores count.
Until players have attended their seventh event, their ranking records both their performance and their attendance (a tracker). For example: two players can have different rankings not because of performance differences but simply because one player has attended more events.
More importantly, below seven events the ranking is a "warts and all" measure. Beyond that, poorer results get dropped and the ranking begins to represent the best of a player.
Confused? I was and I still am. Read on for more detail and analysis. Be warned it's a longish read.
