Expedition Statistics
49 expeditions: 380 people, 778 caves and 2,390 logbook entries.
Number of survey legs: 28915
Total length: 192.1 km adding up the total for each year.
These are uncorrected tape lengths which include pitches and duplicates but exclude splays or surface-surveys.
This is work in progress (March 2023): the underground survey length does not match that in e.g. wallets for 2018 probably because ARGE surveys are not in any of our wallets.
This includes ARGE and other surveys currently. It will be changed to only include lengths surveyed by valid Expo-attendees.

One Survex Survey Block is one *begin/*end block of data in a survex file. Some files from other caving clubs may have a convention of using many more blocks per file than we do, e.g. if the file is exported from other software into survex format.
