When validated the servers select the lowest claimed credit and award that amount. Boinc....Boinc....Boinc....Boinc.... ID: 850651 ·

Cuda takes more Flops to do a larger wu it appears. Hence the over claim.

This would not be tolerated in a third party app. I will have to determine if this is an intentional modification to the stock op count regime, so build new AK_v8 builds to match, if it continues.
