Is current journey consumption just a guess?

I'm asking this cause i realized that accumulated and current journey displays totally different consumption. What i mean is i've done a reset after fully charged and since then i've done like 4 trips of about 17 to 20km. First one showed 15.8kwh/100km second one 15.9, third one 18.2 and the last like the picture shows 18.5. How come accumulated shows 76.7 km and a consumption of 14.7 kwh/100km? Wasn't supposed to be an avarage of the 4 trips?
Sorry for using metric but i'm in norway

I've been thinking about this.

Could it be due to regen....

Accumulated 14.7 kWh/100km or 11.27kWh used.
15.8 / 15.9 / 18.2 / 18.5 = Average 17.1 kWh/100km or 13.12kWh used.
(I know the full trip details are needed to work out the average properly but they sound like very similar distances so total divide by 4)

IF....Accumulated is the amount of actual original battery energy used and, Trip is amount of total energy actually used including what has been regenerated, that would make the Trip higher than the Accumulated kWh.

That all said, I've not noticed that they don't add up (I do reset my accumulated each charge though so usually only have 2 trips on it to average out).
This isn't applicable for your figures as your duration times add up, but remember the kWh does change if the car is on (heating etc) but not moving.

Can some others test this out, make a note of all the trip and accumulated details over few journeys?
Congrats i think you got it. I actually stopped in the car with the heater on about 20 min and maybe that is not being taken into account in the acumulated calculus although in my opinion it should. Good thinking of you..thanks.
