My understanding (from much forum watching rather than actual knowledge) is that when Therion exports map(s) made of scraps (ie not with any maps comprised of centrelines), then the length presented in the statistics is length of 'whole centrelines' associated with those scraps. Unfortunately (perhaps) the finest resolution of the length calculation is on a 'per centreline' basis (as opposed to 'per leg'). That means that the length reported will almost always overestimate the length that is directly 'under' the 'footprint' of scraps exported. So while yes, it is easiest to count the number of scraps authored by each person, it should also be possible to use a similar logic to report the length of whole centrelines beneath scraps drawn by each person. If there are many scrap authors per centreline, the statistic would be worthless due to double reporting of authors for each centreline, but if it is reasonable to assume that mostly a scrap author will draw all the scraps for a particular days survey, the double reporting will be minimised. For surveys that contain only one centreline, the blurring of resolution probably make this a forlorn effort. May as well count scraps per person instead - this is a way of encouraging and rewarding what I consider to be the good practice of drawing short scraps!
