Doing research on Scroll Depth for our website. In workspace, it looks like we have setup metrics and dimensions to determine the scroll depth, but it's not clear that this is the correct implementation. A metric exists for footer scroll and page depth, which both do not appear to be the percentage of the page viewed metric. Dimensions (in red) exist for Scroll Depth - with (Prop17) after it, Exit Scroll Depth (prop17), Entry Scroll Depth (prop17), as well as Scroll Depth Classifications (Exit and Entry). When placed in the workspace, these dimensions return numbers between 1 and 100, but don't seem related to the page metrics being viewed. Am I wrong to think Scroll depth should always be a metric? Any help is appreciated.
