Still convinced my 2018 13" MB Pro Battery is defective

It looks perfectly normal to me. Keep in mind the battery health apps are just a estimate on the actual full capacity/health of the battery. There is always a +/- variable on the actual health percentage of any given battery depending on the heat, current charge level, etc.
Besides that, at almost 6 months and 27 cycles, 97% would seem feasible of a number. Are you noticing any performance issues with the battery, like poor battery life on normal usage?

Everything seems normal, just missed having my %104 etc (sigh). thank you!
[doublepost=1547086322][/doublepost]BTW with the pics I posted I've been running this off battery for 20 min+ (roughly)

Yeah that is normal. The battery should still have plenty of life on it! Enjoy the computer and try not to worry too much about the battery, you enjoy it more when you don’t worry as much on the battery (I used to worry a lot about batteries in my devices).
104% capacity should be a pretty obvious signal that these app things are very much a guesstimate... Just use the thing and don't worry so much, if you think there's a problem take it to the experts if you don't know much about it.
It’s not unusual to have over 100% capacity (factory variation is usually 95-105% of target capacity).
Factory variations, temperature, and a ton of other variables control battery and capacity. You are also expecting the program to be accurate and, well, they’re not the best.
The only way to truly find out is to use the laptop, run some charging cycles (50+) and see if you’re battery is degrading at ridiculous values. Odds are that it’s not.
It is safe to leave it plugged in 24/7, although best to drain the battery every week or so. For what it’s worth, these batteries experience the most strain from deep discharges, so try to keep the battery above 20% if you can. If not, no biggy. Just use it and enjoy it. The computer should give you years of trouble-free, not always plugged in, reliability.
