I updated my GT PE, Sep 21 build, with the latest software (via FDRS and Mongoose) a week ago. Following is confirmation of the improved DC charge rate:
Executive Summary: Despite the cold temps, the charge rate remained surprisingly steady all the way to 99%! Only a couple of percent drop the last few percent of charge. It was only a 50 kW charger, but the 20-24kW rate I saw at -25F was similar to the charge rate step down reported from 150 kW chargers.
Conditions
Sep 21 Build. 1100 Miles. No preheating. Car parked in heated garage 20 minutes before charging. 50KW FLO DC "Fast" Charger. Manual cabin heat left on for most of charge (set to 73F.)
Outside temp during charge -25 F
56F HV Batt temp in garage
39F HV Batt temp at start of charge
45F HV Batt temp at end of charge
78% HVB batt at start of Charge
99% HVB batt at end of Charge
Time to Charge 52 min
Energy Used 20.66 kWh
Following are some data captures from Car Scanner (I spent the time changing Car Scanner default screens, so that data fields are changed between data captures.

90%
95%
98%
99%
Note of Interest: At 98% SOC, I turned the interior climate control to off and the coolant heater power went from 3.82 kW to 5.97 kW. I expected that the charge rate might increase when the load from interior climate was released. Instead the newly available power was all diverted to HVB heating.
