M3 Pro maximum battery capacity is 91% in 16 months of use 😬

I got my M3 Pro MacBook (36GB Ram | 512 GB storage) in Nov 2023 directly from Apple and It’s been my daily driver since then. It stays plugged in 98% of the time in clamshell mode. When I checked max battery capacity on Jan 10 2025, it was 97%. Yesterday I checked and I saw 91% ! I want to know if this is normal. For those who have had the M chip MacBook for 16 months and above, what is your maximum battery capacity ?
