Place is the position among timed finishers in the same race, division and gender; a doubles place is the team's. Runs is the organiser's official run total (it can differ from the eight laps added up by a few seconds), stations the eight stations added up, and roxzone the time moving between them. The age group is the one entered for that race; for a team it is the team’s age group. How the numbers are made.

Each station's best across Kai's Doubles Mixed races, from different races. Typical is the typical Doubles Mixed split across every race in the data. Venues differ (sled carpets, run laps, where the mats sit), so a best can owe something to the venue.
