Theoretically, wouldn't the Adobe single page visits metric match a metric I create where count(distinct page) =1? Both should just be pulling visits where only one page was seen. I also limited it to where only one page and one page type was seen within a visit, but the pre-formulated single page visits metric is still always significantly lower than the metric I created. Would really appreciate any insight into what additional kinds of visits are being eliminated in the Adobe single page visit...
