Ron,
Yes the ORB is the way to go. There is too much fluctuation in what people put, think they need to put, and what they finally end up with in screen shots. ORB compares generally give us the information we need to make a good comparison but as you know even the ORB is not perfect. Missing card clocks or incorrectly detected CPU clocks cause problems of their own so the best solutiuon is to use both.
Remember that hwbot is a user driven database. Each result is not looked at by human eyes as it is submitted therfore we rely on user scrutiny to alert us to potential problems. If you see something you believe is out of the ordinary, report it and a moderator will review it when time allows. As it is now with the example you gave above, hwbot will not block this result. If this score we're in the HOF it is a differnt story, there every score must have an ORB compare where applicable.
