ADLG UK Ranking History

Introduction

Every year I competed, I've checked my Art de la Guerre (ADLG) UK ranking as provided by the British Historical Games Society (BHGS). Not because I'm overly concerned about how well I'm doing, but because I find them statistically quite intriguing if somewhat strange.

How they work

The UK rankings 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.

My record

Despite the above, I've kept a record of my rankings ever since I started playing ADLG in 2017. As the graph below shows I've made steady progress especially from late 2024 to 2025 when I played in a lot more events; this always tends to improve BHGS rankings.
