I wouldn't cross today out just yet. When you offered his food did you make sure it was warm, specifically around the face? (blow dryer or heat lamp method?) Bp's rely on a strong heat signature when striking their food. Was he out when you offered his feeder or in his hide? Did he show some interest?
But to answer your earlier question, it would probably be safest to 'restart' the countdown for successful meals yes. But I'll let more experienced folk chime in with their better judgement.
