Unique climber is calcualted by counting climbers who attend at least one of the events in the target region/division.
The "total" number of unique climbers is calculated based on division level to prevent duplication (For example, a climber attended comps both in R11 and R12 in the season, will be counted both in R11 and R12 but only one time in D1).
Season 2021: Due to the impact of Covid-19, QE is change to a virtual format. The timelines for reopening climbing gyms differ significantly across regions/divisions make the data not directly comparable.
Season 2025: Age category change, JR category now only has one age year (2->1) while D category has an extra age year (2->3).
