<h1>Expedition Statistics</h1>
<p>{{ expoCount }} expeditions: {{ personCount }} people, {{ caveCount }} caves, {{ walletsCount }} wallets and {{ logbookEntryCount }} logbook entries.
<p>Number of survey legs: {{nsurvexlegs}} <br />
Total length: {{addupsurvexlength|stringformat:".1f"}} km adding up the total for each year.</p>
<p>These are uncorrected tape lengths which include pitches and duplicates but exclude splays or surface-surveys.
<p>
<p>This only includes lengths surveyed by Expo survey trips (though not all have valid Expo-attendees as some survex files are administrative collections of *include statements). This no longer (since 30 June 2025) includes ARGE and other non-expo surveys.

<p>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.
