It is more important how close they are to each other than it is what the absolute value is.
I think you did the right thing ... using it as one of several battery health indicators to decide what sticks you wanted to pair up together... the only other thing would be to do the same kind of thing to decide which to replace ... if you reach the point of wanting to replace some.

I agree.

I suspect either back ground charging ... I've seen as little as 100mA actually going into the IMA battery ... but in the low amp range the OEM dash display won't show anything at all.
The other possibility is a positive recall ... the rare but does exist event where the car corrects SoC up.

Keep in mind it is treating the symptoms not the issues that caused them. without modifications to the OEM system ... it is only a matter of time before the core issues recreate the symptoms you just treated... of course you can just do it again.
