75D battery degradation

I’m curious what sort of degradation people have seen on their 75Ds.

I’ve driven 21,000 miles on my Dec 2017 build and my rated range is down to 240 miles at this point. This is down from 245 in the last 1000 miles driven. Per Remote S, I have 68.6 kWh usable. Does this seem normal or excessive?

Anyone else care to share?
I have a June 2018 75D with 22K and I do about 50/50 home and SC. I have been at about 241 miles since about 15K. It hasn't really moved since - I suspect it plateaus there and the degradation really slows down at that point. I think I have 70 usable based on adding 50% adds 35kWh.
 
Guessing I'm at roughly 11%. Early 2017 S75D-née-S60D, 95k miles, 14% SC usage.

Took delivery of a S60D and so I have to adjust my now unlocked 75D numbers back to the locked S60 levels. For these purposes I consider the locked S60 to represent 86% of the unlocked S75 capacity.

High mileage driver here but majority of charging is done on AC, not SC. Per TeslaFi's records SCing accountrs for 14%, or about 4,600kWh. SC will peak around 115kws for me if close to empty but then quickly tapers. Will charge to 100% every month or so but always start driving once 100% is reached - car never just sits at 100%. Normal daily charge target is 75%, if I am not on a road trip.

Current range at 100% is 224. 86% of 224 comes to 193, suggesting a 25 mile (218-193 = 25), or 11.4%, battery degradation based off the 100% range at delivery of the software limited S60D (or 29-mile degradation of 11.4% based off the implied 253 S75D rated range). This is almost a doubling of the loss in capacity from about a year ago, see my quoted post below for details. Disappointed to see such a strong degradation in the course of a year but uncertain if it is solely related to the battery aging or if TSLA's been adjusting usable capacity for safety reasons...I know there's a monster thread on the subject but just haven't had the time to keep up with it.

Current mileage on my car is ~95k.

Took delivery of a new software limited S60D in Jan 2017.

100% range of my S60D - which I consider to be the same as an 86% charge on an S75D - was 218. (This also implies a 253 rated range if my car was delivered as an S75D.)

Since I took delivery I have unlocked the battery from 60 (i.e. 86%) to 75 (i.e. 100%) and my current 100% charge range is 237 as an S75D.

86% of 237 comes to 204, suggesting a 14 mile, or 6.4%, battery degradation based off the 100% range at delivery of the software limited S60D (or 16-mile degradation of 6.4% based off the implied 253 S75D rated range).

Current mileage on my car is ~69k.

I'd say about 50% of my miles are supercharged, and I often charge past 90%
 
I've got a 2017 MX 75D, took delivery in Dec. It's got about 43k mi on it, and at 100% I'm at 214 mi .... this is very concerning. Based on other reports here it sounds like I'm seeing more degradation than others. At what point should I raise this with Tesla?

Probably never. Tesla isn't going to do anything about it unless it fails.

If you are curious and technical I would install the CANBus adapter and watch how closely the individual battery subsections balance. Then run the car from full charge to nearly empty a few times to see if it balances better and if so how range comes up.

Model X 75D was 238 rated miles when new, so you’ve lost ~9%. That’s not particularly bad or abnormal and Tesla isn’t going to do anything for you.
