Micromanaging your battery use is a waste of time.
FWIW, most of the wear on the battery, on a Mac any way, takes place when charging from 20% to 80% or 90% because that is the range that fast charging takes place which heats and stresses the battery. Beyond 80-90% the Mac goes into a slow charge mode at which point it starts to create less heating and stress.
As far as battery life time, some batteries can lose a percentage of capacity quickly early in life and then maintaining tat level for a long time, others could maintain a high capacity for a long time and then degrade quickly, or any other scenario you can possibly think of. It is just the nature of rechargeable battery tech and there is no way to tell how any given battery will last when it is new.
So, just use your Mac and be happy. Generally, by the time the battery will become an issue, your Mac will likely have outlived its usefulness.
