The losses during the charging do not influence to range. The battery has net capacity of 107,8 kWh, that's what counts for the range. The fact that most probably the owner will have take app 120 kWh from the charging station, gives you the proper cost per km, but does not change the range. The issue with the EQS will be the highway cycle, which is barely touched in the WLTP for EVs. ADAC made rhe test on their 'ECO' cycle which also does not include higher speed and it was abbout 22 kWh/100 km for the EQS. And lets not firget, that this is a S class or with other words the class for long highway jiurneys. The city and eco cycles are not for the field of competences of this car. Driving a 5,2 m car in the city is already not efficient due to the size. I'm waiting for a real life test at 160 kmh, where I expect it to have the same consumption as the Taycan.
