Keep in mind that SOH and Hx are values found many years ago by Nissan users when the Leaf first came out. This means the exact meaning and scale (range) are not know to us. Only the Nissan engineers in Japan know the exact details of these numbers. Not even Nissan service people know about these numbers.
It was assumed the max raw value started with 1 followed by all zeroes. This seemed to have been correct on earlier Leafs but now we are seeing raw values greater than this resulting in percent values greater than 100.
Since I do not know what that max value is I can not make an adjustment to limit the display to 100%. Also, if I did make such a change people who have been using LeafSpy for years and tracking these values would all of a suddenly see a drop in the percentage of these values (which naturally drop over time) just because they updated to a newer version of LeafSpy with a different maximum raw value used to convert to percentage.
So it is best to leave things as they are with some people having starting values of over 100%. As their Leafs age the values will naturally drop below 100%.
If you recall the Space Shuttle which had improved rocket engines installed they would always throttle the engines to greater than 100% (105%?) on lift off which just meant the engines had greater power than the early engines. The raw max value had changed so the max percentage needed to change to indicate greater then 100% power relative to the old engines.
