In the Fallout visualization, you can right click on a touchpoint and select "Breakdown fallout at this touchpoint." The result is a table (below) that lists alternate touchpoints rather than the desired one. I was going through this report with a user the other day a realized that the total was lower than adding up the visits for each page. Generally Analytics de-duplicates visits and the like in these circumstances. Because each fallout scenario is based on visits (not visitors in this case), I'm not clear of one where de-duplication is necessary. Shouldn't each visit be discrete?
Does anyone know of a simple example to convey to my users?
If the report is supposed to show the just the next page of a given sequence, how can there ever be duplication? What's an example where there are two sequences where duplication exists and the report must account for it?
