<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 lengths are from surveys which have been recorded in expo wallets. Non-expo surveys done by other clubs, and surveys
|
|
<a href="/survexfilewild">which have not been properly recorded</a>
|
|
in an expo wallet are excluded.
|
|
<p>These are <em>uncorrected</em> tape lengths which include pitches and duplicates but exclude splays or surface-surveys. They are uncorrected
|
|
because they are lengths <em>before</em> any loop-closure corrections done by survex.
|
|
<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 non-expo surveys (ARGE and others).
|
|
|
|
<p>Authoritative survey lengths for each cave are calculated using <a href="/handbook/troggle/cavelengths.html">a script</a> which uses the
|
|
<em>loop-closure corrected</em> lengths and is manually curated to exclude duplicate surveys of the same cave. The results are maintained
|
|
in an <a href="/repositories/loser/.git/tree/docs/smklengths.ods">ODS-format spreadsheet</a>.

<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, but each block is recorded on a single day.
|
|
<p>Currently the number of cavers includes non-caving attendees: that needs to be fixed.
