Model X 90kWh battery pack degradation

Took a road trip to Idaho and back (1600 miles one way). I charged at my first V3 SC. I was very impressed with the charge rate.

My December 2016 Model X P90D Ludicrous charges to 204 miles at 90% and 227 miles at 100% . This was tested with home charging. It has 69K miles currently. I have no information about how the previous owner charged it.

Supercharging : This P90D can pull 154kw from the Malibu V3 supercharger, state of charge was showing 60 miles. By the time it showed 80 miles it was down to 130kw.

!!! My 75D MX (Yes I know it's not a performance Model) gets 210 !!! Though peak charge rate is now 114 and once it hits 50% charge rate hovers around 60kW as a max. (101,000 miles on the ODO, November 2016 Build). CAN BUS data shows the 75 pack is about 66kWh capacity now.
My 90D Model S on the other hand, was 294 new, now 248. the 90 pack according to CAN BUS data is at about 73.2 kWh capacity. 115,000 miles on the ODO.
 
P90D made in 1/16, delivered in 3/16. Battery 1056776-00-C. Mostly charge at home but some long road trips with supercharging, several to 100% because of the range. Now 50,500miles.

I also have a P90D made in 1/16 , also with battery 1056776-00-C. I also mostly charge at home but with a little supercharging. I have charged it to 100% a handful of times in the last year. My mileage is also a little over 50,000 miles.

In the last year a 100% charge has gone from 228 miles to 225. Note this model had a range of 250 rated miles when new. So exactly 9% degradation by that measure. But also note only ~1% of that happened this year.

ScanMyTesla reports a Nominal Full Pack of 75kWh (varying between 74.9 and 75.2 depending on calibrations, temperature etc)

Out 90D VIN is 001900's Q1 2016 has 60k on the clock and reports 70.8kWh Nominal. We see about 220mi rated range. Started at 270. We took the car in countless times early in ownership, left the car with them for probably 3 weeks working on the issue. Finally, we were told suck it up, too bad back in about Oct 2018.
 
I've seen 132kW, which is really impressive when you realize that I had a bad condenser fan at the time, so the cooling system couldn't run at full capacity. I'm curious what the rate will be now that it's fixed.
Following up to myself: this last weekend the best rate I saw was 161kW, and it sticks around over 130kW for a good long while.
