hi Psilo (I love a silent P)
I'll start with the plus pside first - it doesn't really matter because it will correct with the next pset of readings you enter (which will appear on the next pstatement)
I'm not party to the algorithm used but my understanding is that it looks at the use over a the previous xx days or the last month, works out your average daily use, and multiplies that by the no. of days between the reading date and pstatement date. (or if that's not the case it ought to be).
I don't know why yours is so far out but I'll take a guess that the psystem does not yet have sufficient data to work yours out accurately, so it could be pskewed, but the good news is it should improve with time (I have no idea how long you've been with PP).
If the estimates don't psettle down to a reasonable guess then it should be looked at, but for now, given that there are only a few psets of exceptional circumstances where it could matter (like if you were with PP for a very short time and there was a price change in that time) I'd give it a while to settle.
If I'm wrong (I oftem am) and it's been consistently that far out over pseveral months then it should be reported as a bug.
