I think the problem is a misunderstanding of what these pages are displaying. While it may seem like credits are being double counted they are not, but all the pages you listed show a different way of counting/displaying credit amounts.
Crunching@evga member list
http://boincstats.com/en/stats/-1/user/list/0/0/e73e23eba5fc3bc0d57b3c43c097d1a9/
This is a listing of all people associated with team crunching@evga and
their personal combined credit count. At BOINCSstats for combined pages you are associated with the team you have the most project team memberships with. This display of user totals within a team is the same behavior for teams at individual projects.
crunching@evga charts
http://boincstats.com/en/stats/-1/user/detail/2912267/charts
This is actually your personal account charts.
This link is the team crunching@evga charts --
http://boincstats.com/en/stats/-1/team/detail/58913125/charts
I am not sure what issue you were trying to show with the charts link. But if you look at the team charts you will see the credit production dropped on Nov 23rd when you moved your BU account to a new team.
mining@evga with all the points as well
http://boincstats.com/en/stats/144/user/list/0/0/2124/
This is the team mining@evga project listing. So yes it correctly shows the members of the team and their
current total project credits, just like you see on the project team pages.
If you look at the team details page
http://boincstats.com/en/stats/144/team/detail/2124 you will see that the current team total of 1.6B is less than the total of the two current members 2.6B because some of the credit had already been assigned to a different team.
If what you are asking for is how to get that 1B of BU credits off the team crunching@evga listing then you just need to delete the team on the BU site and wait a day or two for it to vanish here as well.
If what you want is for your BU credits to not be included in your combined total shown on the team crunching@evga listing then, as you pointed out, you need to use a different email address at BU so you get a different CPID.
