I'm using Analytics 360. There is no remark/note of sampling appearing on the report, so I assume it is a result from complete data --- but then it's a puzzle why "new visitors" pay more sessions (163401) than "total visitors" (154824) do, which seems to be the conclusion of below 2 reports: the difference of these 2 reports is simply that I added default segment "user type" as a secondary dimension in the 2nd report. I hope someone can help with this puzzle, many thanks!!
