My confusion in what you asked, but over my last to posts I had hoped it was clear that:
A. I don’t believe the two figures should be in the same area
B. nor do I think they are the same, an average against the number of user scans done as my figure appears to be total not average scans I have done.

For me it is a bit like comparing apples and oranges, if one figure is an average, then really the other should be an average and there is no way my Blue column is my number average of monthly scans.

Running a scan whilst compiling this topic and others, both my figures are 9, so there is no way the Blue column user scans is an average but a total, see image. So that needs to be made clear or they should be separated by some white space between them. Better still the Blue column should have the same Tool Tip displayed outlining what it is when you hover the mouse pointer over it in the same way as for the Grey column.
