AC Charging Loss on iX3 from power supply to car?

Interesting article on AC charging losses for a few EV car models in Europe.

https://www.adac.de/rund-ums-fahrzeug/elektromobilitaet/laden/ladeverluste-elektroauto-studie/

Losses using 11kW AC chargers ranged from 5.1% to 7.0%. Charging at the household socket with 2.3 kW was much worse, 12.7% to 24.2%. I was just wondering if anyone had estimated the AC charging loss for the new iX3 at 11kW levels?

Hoping BMW made some improvements over the competition.

(My iX3 is not due in USA until early October)
