Qualifying named-brand observations

At category level, the lowest current averages come from major brands for Petrol (E10) and Diesel (B7). There is not enough current supermarket or major-brand coverage to identify a named operator leader. major-brand prices are 0.4p/l above their 30-day averages on average. There are no independent forecourts with comparable current prices in Knelston, so that category cannot be judged fairly yet.
