Don't obsess over stuff like that. Unless you have an issue with the batter not performing as-expected or you suddenly see a drop in performance, you'll probably be happier if you just don't look at Coconut Battery.
Yes it looks ok. As long as there are no rapid, significant drops, you are fine. Fluctuations of couple % are perfectly normal with industrial batteries.
Yeah, it looks fine. But really, I’d say stop looking at it. Just use and enjoy the system instead of obsessing over things that don’t actually matter at the moment.
When you start to encounter issues, or your battery life suddenly and inexplicably depreciates, then start to investigate the why.
No good ever comes from looking for problems that don’t exist
