Important thing to note is that each daily average figure I think is volume weighted (it's certainly not the mid-point between the low and high price of each day), but the rolling average is NOT the volume weighted average of the daily average prices. Something I might try to add. Still, the average price received for gas for the year so far, has to be somewhere around this rolling average figure I've calculated.
Also, what price did Serica sell its gas for on each day in question, we don't know, but we know it must be at least equal to the lowest price paid on the day.
