[bug?] MPG calculations are wrong

Yes I am using odometer to track.
I thought a partial fuel up is when I partially refill my tank (but always keeping track of the odometer).
What do you suggest then?

Thanks


EDIT: this is the bug I am talking about.

You can see from my log for example that the calculated average L/100 is 20.48 because it is the result of this operation:
(26.861*2+27.172)/395*100
whereas it should be calculated
(26.861*2+27.172)/(395+515.01+468)*100
with all the KM!!!
