Help understanding my Goal Flow
The below Goal Flow describes my Checkout funnel. I am trying to understand if the numbers there are "Users" or "Sessions"
1) The Segment says All Users (100% Sessions) - I don't understand this?
2) If you look down in Step 1 "Cart" - it says 3.1K, is that number Users or Sessions ?
3) Why does "Cart" (on the Green box) say 3.5K, and down in the tables the total is 3.1K ?
Thank you very much for clarifying how to properly read and understand this report.
