What's your 90%?

Does anyone else see their 90% go down a bit in the fall and go up in the spring? I thought my battery had degraded last winter when my 90% went from 268-269 down to 266-267. Then when the weather got warm it went back to 268 most of the time, sometimes 269. Now it's back to 266-267.

yeah that is normal, colder so higher kwh/mi usage thus lower range reported based off usage
 
Looks like my 90% is 209 miles in a 75D that began life as a 60D. I've read other posts from owners who have had the same software "upgrade" who aren't thoroughly happy with the result. Is anyone getting near the EPA 257 miles on their 75D ?

My S75 (previously 60) has a 90% of 203, 100% is 229. 31k miles.

Higher degradation than I was expecting, ~8% so far. Hope it levels out soon.
 
Should I be concerned?

My 2015 P85D with 55K miles only charges to 217 miles at 90%. It has 21" wheels. This is much lower than my previous P85 with 21s. Any feedback is appreciated.
My 85 has been 221~222 @90% for a long time. A little less than most. The P85 was rated the same as the 85. The P85D may be rated a little less efficient, not sure. If it's dropping, that's a bad sign. If it stays consistent for a while it's probably fine.
 
Pretty much all Model S P cars are less efficient than their corresponding non-P variants. This is due to the larger motors and to some extent the driving style of the owner.

My P90DL had 242 rated miles when new. It now has 235/236 some 20 months later which is about a 3% degradation.
Regarding seasonal efficiency, from what I have seen the HVAC load of heating the battery, seat heaters, defrosters, steering wheel heater and the cabin heaters during colder weather does account for somewhat greater watt hours per mile in the winter. However I have not see this reflected in my Rated Miles calculation.

TeslaFi has a great chart that shows your S's efficiency over various temperature ranges.
 
S75 217 miles is about what I'm showing. Interesting enough TESLAFI also calculates in the 100pct estimated range on these 90pct cycles. For reference, 9/11 is when we took delivery. To date our mileage is at 5,600 miles.
