It's going to be a few days. I'll need to have time to run the battery down, let it cool and then drive over to the SC without letting it sit low all day. How long is enough to let it cool?

If you've run a heating cycle, I'd give it a few hours. Otherwise, it doesn't seem to make much difference whether the car has just been driven 3 miles or 150 miles to reach the SpC.
The info I gave earlier was without using the max power option. It was just a bunch of driving beforehand, which is what I thought you were originally referencing.
Now that I have the API working next time I charge I'll do 1s pulls and have more accurate numbers over time.
Ah, ok. Then I'm really not sure how to explain it. If the numbers are reproducible with the second go around then I'm inclined to believe Tesla simply hasn't gotten around to optimizing the taper curve on the 90.
I'll drop it down further. This time I'm going to be recording 1s intervals from the API so I'll be able to just grab the time I get the data back. So this time it will be a lot easier to process.

Pete and Troy, There is no need to include the clock in the pictures - as the iPhone records the time each photo was taken.
36K miles and the charge is lower now.
59%=69KW vs 74KW
63%=60KW vs 66KW
77%=43KW vs 48KW
83%=37KW vs 40KW
So there's a big fat difference in teh middle of the SOC range with it narrowing on either side of the taper.
Is this due to battery aging and software deciding to take it easier on batteries that have been charge a certain amount or did they change the software to charge slower after the fact.
@sorka - It was widely reported that Tesla enhanced the supercharger rate to hold 100 kw well past 50%. Was your 90 kwh model unaffected by this firmware update? Happened last year.

I have a P85DL. That's interesting given that when the 90 was first released there was a little bit of an uproar over the charge rate being slower than the 85 despite being a larger battery.
I was above 100KW until around the 50% mark.
