I’d say your SoH difference is well within system tolerance but if you’re bothered about it repeat your battery calibration on a warm summer’s day and all will be fine..
According to EV database a Mk1 has a usable capacity of 42.5kWh and charge efficiency is about 85% (if it’s similar to our MG5)
In order to fully charge a new battery (0-100%) 50kWh is required or about 47kWh from 6-100%. Less for a battery with a reduced SoH, in your example (88.4%) I’d say...
It’s been comprehensively proven by many EV owners that it’s perfectly fine to regularly charge an NMC battery to 100% without experiencing noticeable battery degradation.
By all means if you can do your driving with 80% of the ‘tank’ stick to the recommendations, however if your struggling...

Depending on the version of the Supercharger, an upgraded MG5 needs to be either off (older Teslas) or in READY and start charging from the display in-car (newest additions with CC readers?)
