Okie doke, if the decision is to stay with that then I'm fine with it. Given I understand now, it's not a big deal for me either way. I still think the bottom should be labeled Net Won Game (bb) since that's what it's representing, but I'm just one person.
This issue can be considered closed.
Yes, we (support, testers, QA) are still discussing it to see what we can write up for the developers to try and make it more clear for both you and us. We should be able to add some detailed text to the column headers of the upper and lower grids as needed, I think, to differentiate them without the need to hover for tooltips, hopefully.
