Have you simply considering doing real life range test? Fully charge and then drive the car to VLBW (or turtle, if you are careful) and what your capacity seems to be? There's a big range difference between 8 and 11 bars.
i have done a range test. Before I got about 60 miles to LBW and another 25 to turtle. Now I get 80 to LBW and another 10 to turtle. I estimate 1kWh improvement in total capacity.

Had the need for a full charge this past weekend and grabbed the following stats.... software update was done the evening of 6/20. Car is a '16 30kWh. Battery pack mfg date is 12/15. Here's hoping that another 1.23% SOH drop does not happen after another 584 miles.

Date 6/19/2018 6/20/2018 6/21/2018 6/23/2018 7/3/2018 7/21/2018
AHr 68.58 68.51 73.66 74.27 73.94 72.96
SOH 86.29% 86.20% 92.68% 93.44% 93.03% 91.80%
V 395.67 395.47 395.26 395.66 395.71 395.55
Hx 78.79% 78.70% 78.28% 79.79% 78.98% 76.54%
ODO 32561 32589 32643 32830 33303 33887
QC 9 9 9 9 9 9

SOC 97.80% 97.70% 97.80% 97.70% 97.80% 97.70%
GIDS 313 313 337 339 338 334
kWh 24.3 24.3 26.1 26.3 26.2 25.9

On the bright side, in some very mixed highway/city driving I got 104.7 real world miles (22.8 kWh used / 4.6 miles per kWh in 3 hours of driving).

A charge to full from Turtle would be less susceptible to variation

Charging from turtle before and after showed a 1kWh improvement.

Interesting, and thanks for the information.

Do you happen to know if the LeafSpy reported SoC at VLB changed after the update ?

VLB is at the same number of GIDs but SOC in LeafSpy is much higher. At turtle SOC still reported 5.7%. Prior to update SOC at turtle was 0.0%

Useful info. Prior to the update did you notice when SOC first reached 0% (how many GIDs)?
2014 S - 6000 km Jan 2016; 45000 km May 2017 95% SoH; 68,000 km Mar 2018 90% SoH

Prior to update up to 6 GID = 0% 9 GID =1.3% 41 GID = 11.5%. Now 5 GID = 5.7 and 5.4 %

Incredible! ~ +6kW (~ +16 Ahrs, ~ +20% SOC) after the update

Amazing what one can do by changing a few binary numbers, right?
Leaf SL MY 9/13: 66K miles, 50 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 charges to 100% > 1000, max battery temp < 95F (35C), min discharge point > 20 Ahrs

Did I miss those results ? They are the most indicative of whether the post update Ahr capacity increase reported by the BMS to LeafSpy is believable.
