Yes sir at least on multi GPU boxes ... it is always correct for a single card. You can open the wu record as I said and get the start time and stop time and you will find that the reported time is 2x or 3x(depending on # of GPUs) higher than the REAL time. I don't know what causes it because like I said I attached and ran for someone else and the reported time on the 6990 was correct. When I moved it over to my account then the time was double what it really took. Go figure!
