Calculate Geometry — Number of vertices should match Edit Vertices pane

[Bud]

ArcGIS Pro 3.2; Mobile Geodatabase:

I have a four-sided polygon in a feature class. When I use Calculate Geometry to get the number of vertices, the result is 5. Yet, the Edit Vertices pane shows only 4 vertices.

Likewise, the Attribute pane's Geometry tab shows 4 vertices.

Best guess is: Calculate Geometry considers the end/closing vertex to be a true vertex. That seems like a strange approach when counting vertices. I understand how that could apply in the back-end, but when counting vertices from the user's perspective, I wouldn't think to include the closing vertex.

Could that functionality be changed so that Calculate Geometry only returns 4 vertices, not 5? I think that would be more consistent and intuitive for users.

Or alternately, could the Edit Vertices pane show that 5th coordinate?  Maybe even with some non-numeric character in the # column, like an 'F' for 'Final'.
