Real world miles per kWh?

Tesla Model S 100D (13.12.2017) EAP, FSD, AP2.5

Winter 2017/2018 average = 23.4 kWh / 100 km (2'207 km) = 375 Wh / Mile
Summer 2018 average = 17.2 kWh / 100 km (10'331 km) = 276 Wh / Mile
Winter 2018/2019 average = 21.3 kWh / 100 km (8'502 km) = 342 Wh / Mile
Summer 2019 average = 18.8 kWh / 100 km (10'240 km) = 302 Wh / Mile

1 Mile = 1.609 km

i’m just wondering what you guys are getting miles per kWh?
2017 MX 100D, lifetime of 339Kwh/mi

For me at least, temperature and tire pressure seems to play a large role. On days when its over 55F, not raining, and my tire pressure is 44 or higher, i generally get better than the rated range. If the temps are much lower, especially if I have to run the heater, then i see well over 400Kwh/mi.
Depends on the conditions and the type of journey. In our MS70D our best long journey worked out at just under 4 miles/kWh which combined A roads and speed restricted motorways. 70-75mph cruising is about 3 and a bit miles/kWh.
My wife's 15 miles each-way commute is more like 2.5 miles/kWh.

Model 3 will do better as it's lighter and has less drag (lower frontal area).

We've only had our car for a week under 6 months and we live in the South so we haven't experienced very cold weather yet but I'm told efficiency can drop by 15-20%.
