The chart is not compiled by the OCC, but by a company called Millward Brown. They are, according to their website, "one of the worlds leading research companies" :cheer: . Perhaps we should be contacting them about the Dualars single? I wish someone could explain exactly what happened. CliveR, if you have all the facts, please reply. Robbie, you seem to know how the chart runs. Can you tell us all about it?
