EQS580 Charging speeds error by MB?

Did anyone notice Mercedes made a mistake on the EQS 580 charging speed? If you do the math 240x32=7,680 (7.6 kW) and 480x300=144,000 (144 kW)
My Chargepoint Home Flex is set for 32A on a 40-amp circuit and I'm getting 6.7 to 7.6 kwh which is about right. To achieve 9.6 kW we would need a 50-amp CB and set Charge Point HF to 40A (240x40=9,600 (9.6 kW)

How did MB get the values below?

From MB website;
AC charging speed (240v, 32A) 9.6 kW
DC charging speed (480v, 300A)
200 kW

The 9.6 kW speed is correct. It's the 32A value that should read 40A.

Correct, the EQS SUV can handle up to a 240v 50A breaker which provides 40A continuous (80%) or 9.7 kW. Anything higher is pointless since the onboard converter will cap it at 40A/9.7 kW.
