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.
I have written about rankings before in 2023
(see the postscript).
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.
