How are the monthly figures worked out?
From the daily national average, the mean of the price readings recorded that day (one per forecourt, plus one each time a forecourt changed its price) with readings too far from that day's median to be real left out, with each day weighted once. Days with too few readings are left out rather than averaged in, and a month is only listed once it has ended.
Where you are, the national average matters less than the forecourts near you: see fuel prices by town, and the daily trend for the month so far.
