I'm closing this case and my interest in the matter. I'll just chalk it up to some sort of rounding error in the app math. When the actual charge percent is 69% it does the funny -1% limit setting math. When the charge is at a solid 70% or higher, it works correctly. If it ever gets worse, changes or otherwise becomes a (problem) I'll bring it up again.

Slider for charge percentage not accurate?

Mine is really bad when the car is below 20% SOC
At the 50% mark its only showing 40% charging capacity .
At 100% mark its showing only 90% charging capacity.
When the car is charged 50% or above I get the -1% to -2% error.
But when the car is at a low SOC it has really large error or -10%
But if I leave the car to charge to the 50% mark it will show 50% when its charged so the error goes away.
It is very strange.
I have done under 3k miles and I have a perf M3.
No supercharging ever. Only he charge at 7kw
I've tried charging to 100% and left straight after it hit 100% and drove until under 90% it didn't help.
As you can see this is the lowest I've been in SOC. Always charging nightly to 80% or 90%
I'm trying to get to around 5% soc and recharge to 100% and see if it cures the problem.
I dont do this regularly at all. As I say I only do short journeys and charge nightly usually.
I'm just doing this to hopefully recalibrate the BMS.
If it doesnt cure it. I have a SC appointment booked in.

Hmmm, I am going to bet that the OP is really Adrian Monk and bothered by odd numbers 
Frankly speaking, I guess I am sometimes a little big OCD too
