How far did you travel from the fill-up to your home? What sort of roads and how many stops, traffic lights and roundabouts are there? Was the engine still relatively cold?

If the engine was still cold that could explain it. If it was hot then, yes, providing the speed was high enough it could have started regeneration. Otherwise don't know. An average over only 15 miles from reset can be very variable.

Are you resetting the trip in between journeys or is that a cumulative figure?
