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. "6 of 8" marks a stations total from the stations that were timed; the others had no split at that race. 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.
