Wow, that's really good!!
I'm close to 45k miles now, and the range has been steady at 245 rated miles for almost a year now, or the last 22k miles (range mode always on).
My 90% has risen from 224 back to 226 which is 1 mile less than it was new at 227. Thought it might go down again when it got cold but it charged again this morning to 226 with in the 40s in my garage. We had a hard freeze last night.
My 100% last week went to 251 which is 2 miles less than the 253 it was new. I saw a few 250 charges back in June at 100%.

Are these figures with range mode ON or OFF? How many miles do you have on your car now?
With temps falling in the Bay Area now, I charged to 100% before my long thanksgiving trip and only got 243.55 rated miles with range mode ON. So that's about 240 with it OFF, which means I'm down 13 miles from the 253 rating when new (5% drop over ~44k miles).
Range mode on. I never turn it off. With range mode on it charged to 227 @ 90% and 253 @ 100% brand new.
Some speculate that Range Mode decreases battery temp management and may have harmful long term effects and should only be used when necessary to scratch out a little more range in exchange for not using energy to manage the battery temp as closely.
Interesting finding about Range Mode
hmm looks like ours has lost more range than most, June 2015 P85DL, currently approaching 40000km charges to 347/383 at 90/100% (that would be 215/240 miles). (that's all with range mode on)
When new it was more like 238/252 miles. It fell last Winter, the SC said that it should recover in the summer but that never happened.
On the other hand the loaner P85D they gave me during some service in Spring was charged to 100% and that was 388km so not much different.

2 years and 20,000 miles on my Nov 2014 build P85D. Just did a 100% charge: 251 rated miles. Pretty happy with that as it amounts to only 2 miles lost to degradation in that time, or 0.79%.
I've noticed I get a higher number when charging from low single digits all the way to 100% in one go, vs. charging shorter ranges than that.

Just as I read your post I was doing a range charge due to a long trip planned for this AM. I thought about your post and decided to remove my code ection when it showed complete and 100% then plug in again. My rated range increased from the Typical 247 miles to 252 after another fifteen minutes charging. I am confident there are some rounding errors and algorithmic quirks when measuring range, especially at extremes. Anyway, I am very happy with my battery performance...

Just had a P85D loaner with 32K miles, 224/243 (90%/97%) - picked up the car with 97% SOC. Range mode OFF.

Interesting. I charged to 100% this morning and saw 247 miles.
Charged back up to 100% this afternoon after a long drive that used 80% and saw this. Not bad for 2 years and 21,000 miles (was 253 miles new)

In addition to rebalancing, the rated range will vary slightly with temperature. If you charge in the morning to 100% and it's cold, you'll show slightly fewer miles than when the battery is warmer at the end of that charge do to it being warmer outside and the battery starting warmer since you already drove it.
