Drive data | kWh & Wh/m

Hello

I’ve just subscribed and am getting my head around all of the great data available! I have a question about the drive data. 

Yesterday I travelled for 94 miles and the battery went from 89% to 49%. The drive data like kWh used and cost all looks too low.

That evening I added 27.5 kWh going from 48% to 85%. 

In order for the drive data to match the charge data, the kWh & Wh/m Factor in settings needs to be around 1.46. This is much higher than the average of 0.94. 

I have a M3LR dual motor, which is just a few month old. The trip was mainly on a UK motorway at about 13C.

Any ideas?
