Charge Efficiency over 100% for 50kWh charge

This was an hour plus charge at an Electrify America Chademo running around 48kw.  TesalFI shows a 102% charging efficiency.  Wouldn’t this mean I received more kW than EA sent?

I saw a two year old similar question but that was a short term charge and something about lost data. This was a long charge that is recorded correctly, just the odd over 100% efficiency.
