I am starting to think otherwise.
Correct, your initial estimate was unrealistic. It goes like this:
242 km range from 100% -> 0% when car is new, no headwinds, good roads, good weather, and about 105 kph speed.
In your case,
You have lost 5% range already;
To avoid range anxiety you want to reach your destination with 10%
Include a 10% buffer for wet roads/headwinds
Expect a 15% lower range to travel at 120 kph instead of 105
Added all up...
242*0.95*0.9*0.9*0.85 = 160 km
Winter will be 10 - 30% less, depending on choices that you make. Then range will be as low as 160*0.7 = 112 km or as much as 160*0.9 = 144 km.
You have two good mitigations:
Find charging during the day,
As the battery loses range you will become ever more dependent on same day charging.
As for really bad winter weather --- well, plan for the worst and don't be surprised if you have multiple charging stops
