I don't know what your "best case scenario" is, but it's useless.The photo you posted showed 1.2 m/kWh. With an extended range battery (131 kWh) that's a full charge range of 157 miles. That's about a 50% range loss from best case scenario.
The valid comparison to calculate winter drop is to compare to driving at 77 degrees on the same route.
I get 1.7 to 1.8 in warm weather. I get 1.3 in cold weather. While that's rounded numbers, the drop is pretty clearly 24 to 28%. No where near 50%.
