139	Report multiple matching 'triplet' legs where readings are too divergent	Wookey	Olly Betts	"Survex will concatenate repeat legs between the same stations, as is typical for paperless surveying (3 similar-enough readings makes a leg). However it currently assumes that the legs have already been checked for similarity, but of course it's possible for them to have significantly divergent readings and that should be reported as at least a warning.

This leads to questions about what tolerances to accept. Pockettopo, Sexytopo, Topodroid, DistoX2 and SAP6 all have slightly different criteria for matching legs. Survex already has defined SDs for the readings and should probably use those to derive 'close enough' criteria.

An example of a dataset containing repeat legs that do not actually match is 'cathedralchasm2.svx' in the Austria loser dataset: https://expo.survex.com/repositories/loser/.git/tree/caves-1623/264/cathedralchasm2.svx"	enhancement	new	minor		cavern
