<h1>Expedition Statistics</h1>

<p>{{ expoCount }} expeditions: {{ personCount }} people,  {{ caveCount }} caves 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>
This is work in progress (March 2023): the underground survey length does not match that in e.g.  
<a href="/wallets/year/2018">wallets for 2018</a> probably because ARGE surveys are not in any of our wallets.
<p>This includes ARGE and other surveys currently. It will be changed to only include lengths surveyed by valid Expo-attendees.

<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.
