My 2011 when set to charge to 100% actually just charged to an SOC 91.71% but that is only 205 Gids or about 73% of the original capacity.

When new SOC was around 95% at full charge. So if you just looked at SOC change I have lost only 3.29% which is obviously not the case.

As a Leaf gets older SOC is of less and less value.

It does benefit Nissan as customers can not really see battery degradation in the SOC number now displayed on the dash. Someone buying a second hand Leaf would probably look at the SOC at full charge and think everything is still ok.

That can happen between 4-8 Gid typically. The app should use 6 Gid as a relatively predictable middle ground to show zero miles remaining.

So, does "Percent GIDs" work that way, or is that one constant over time?
i.e. if my battery degrades about 25% in 3 years, the max percent GIDs at a full charge would be somewhere around 75%, where as SOC could still be in the 95% range?
