You worry too much, just enjoy the bike now when its back together. I’ve been there as well and as soon as you realize this, life is lot easier. Different manufacturers show battery’s health different ways and now your talking about 1% difference
Don't worry about it. "Battery Health" is an arbitrary number calculated by each manufacturer and their pointy-headed software scribblers. No one really knows exactly how the number is derived. Call them up. Ask them. You won't find anyone who knows.
But if you have a bike with 1600 kilos and it's telling you that the battery is as good as the day it left the factory, then THAT is the data you need to question.
