I was always running over %100-%104 but after 17 cycles I see this going down. I have the one year manufacture warranty and am enclosing two screen shots 1 - Battery Health App and 2 - coconutBattery.

Is this even worth taking into the Mac store? Also if I purchase a battery from iFixit will this be better and also work with the new T2 Chip without any issues?

Yup the OCD kicks in. With my 2017 MB Pro Apple was able to fix the battery plus the logic board for free.

Apologies if this is redundant just want to know why I went from %104 to 99 which sometimes goes lower.

Thank you!

The answer to your title question is no. Your battery appears to be fine. I don't have any experience with ifixit batteries but since the battery in your 2018 MBP is glued down, there is likely no way you would be able to replace it yourself. Make a genius appointment if you like and see what they tell you.
 
I’m sorry you’re taking the brunt of this upcoming rant but MacRumors really needs to do a sticky thread on battery “health”. There is a frustratingly high number of these threads.

Batteries are consumable items. They will always eventually deplete, regardless of usage or cycles. Stop checking the battery health because it encourages paranoia and ruins the enjoyment of the machine.

The “health” of a battery (an arbitrary estimate) can also fluctuate based on current temperature, current charge, or Jupiter’s alignment with Saturn. There will not be a discernible difference in battery life for anything above 90% health anyway.

These tools are useful for confirming a buggered battery, which would be glaringly obvious anyway if you’ve been struggling with battery life or get a “service battery” warning when the OS detects it hits its failure threshold. Otherwise, delete the app and enjoy the device.
 
From Apple's One Year Limited Warranty:
This Warranty does not apply: (a) to protective coatings that are designed to diminish over time or batteries, unless failure has occurred due to a defect in materials or workmanship;
 
Thank you all.....just going to ride with it....it'll only diminish over time anyway but it still packs a great life-span :)

Can confirm, Jupiter was to blame for my issues, or was it Saturn...
