When you put the vehicle in park it "finalizes" the numbers. It does not zero out the numbers until the next time you put the vehicle in drive (you must also exit the driver's seat to initiate the reset of the "drive" trip meter).
I came back hours later for that number, it wasn't reset, but yeah must have added a bit.
That will improve your efficiency on a 2-mile trip by approximately 90Wh/mi (115ft*1.6kWh/1000ft/2mi). So your baseline is about ~205Wh/mi which seems like it could be about right for an LR AWD at low speed.
Let us know about the return trip in the exact opposite direction! I would expect about 290Wh/mi.
Yeah the uphill is definitely more, it's hard to say because it always starts with a very high number that comes down, so when I leave at first it's like 700Wh/mi after a few minutes this becomes 300Wh/mi and then slowly drops from there, but then I hit the hills and it brings the numbers down again. It maybe because I live in a Condo and don't charge every night? + Sentry mode is always on which is a drain, I wonder if this plays into my large starting no.s??
I've got a new low of 102Wh/mi - I'll post it shortly.
