"A wide discrepancy was reported in the 40-yard dash times today, as the NFL Network widely reported several very fast times for players, while members of the National Combine Service, who runs the event for the league, released times that were much slower across the board." As per that site jterrell posted. Just thought it was interesting. I thought those 40 times seemed awful fast. I think the NFL Network has started putting more emphasis on the "unofficial" thing because of this.
