Charging 10%-100% every 3-6 months

He didn't give any evidence. I queried it in the comments but I don't think he got back to me. Seems like overkill to me.

Has anyone seen any OBD-reported SoH improvements through slow (single phase) 6A charge?
It's Well known way to balance battery More on Jaguar I-Pace to drop power to 6A around 97-99% soc. It does balancing sometimes for 2 to 3 hours until highest cell reaches 4.13V.
Might try on my 2023 with 50000km on it with OBD reported SoH 96.4%

No, but I’m curious to see if an AC charge from below 10% to 100% in one go will indeed change SoH (don’t think to go as low as 6A is actually necessary).

I managed to calibrate my BMS courtesy of EDF energy Sunday saver. 16 hours of free electric by cutting my peak usage down from 12% to 4% for a week mon-fri. I get about 10% per hour out of my 7kW charger so it took about 9 hours. I used the other 7 hours to top SWMBO's MG5 up.
FWIW, I was looking online for a solution when my new phone kept dying at 30% charge and it seems you can calibrate the battery by flattening it, letting it rest, then charging it to 100% without interruption then leaving the charger on for a couple of hours.
This struck me as very similar to what we are discussing here about calibration of the BMS, so I thought it maybe better to charge it all in one go ?

Did your SoH change?

Regardless, is that terrible if you charge at peak rate for half of a full charge once in 6 month?

I don't know uk electricity market, but in Italy with Octopus peak and of peak rate are just matter of 0,03€ difference.
Even with a way bigger difference we are speaking about 30ish kW/h.

I didn't check it then, but checking it just now it's 96.8% SOH at just over 2.5 years old and 70% SOC.
