Martin Is this because the statistics are resolved by Therion centreline object by centreline object, and not leg by leg?
Or is the problem you describe different? See bds [Therion wiki] <https://therion.speleo.sk/wiki/bds?s%5b%5d=statistics> and the map object survey option described on pages 34-35 of the current Therion Book. Perhaps something like… Map MyMap -survey MySurvey will align the statistics as you want. Bruce From: Therion <[email protected]> On Behalf Of Martin Kern Sent: Sunday, 15 February 2026 07:34 To: [email protected] Subject: [Therion] Difference of length in legend and statistics Hello, Is there a way to display in the legend of a map the total survey length instead of the total maps length? I have a survey where the total cave length shown in the plan legend is smaller than the total length displayed in the statistics (the statistics file is correct and there are no duplicate surveys). I cannot understand where the discrepancy might come from, but I suspect it is related to the maps (I have some surveys that do not appear on the plan and for which there is no .th2 files). Thanks, Martin
