I agree Martin, one survey file, one trip. However we just did a survey of three small multi-entrance caves and overland surveys over a couple of days. In hindsight we were a bit messy in practice as we surveyed into one cave and out of another entrance and into another cave, then back out to the first cave etc etc. What I found was that Therion could not (or I could not get Therion to) adequately resolve the statistics for the caves individually until I split some of those surveys into two or three. It also would not separate surface survey statistics from cave statistics (but I think that is a bug). Statistics are resolved correctly for maps but not for survey-list. So as a last resort I cut the survey trips into multiple surveys/files. If I had drawn the scraps before doing this I would have had a difficult job patching it all back together. An unusual situation perhaps, but one where manipulation of the survey files was able to lay a better foundation on which to build scraps and maps.
