Did a low range test

So today I decided to see how low I could take the Bolt on charge. I started out this morning with 28% SOC on the My Chevrolet app with 80 miles of range left.
I had driven 175 miles at that point starting out with 87% charge.
I ended with 2% SOC on the my Chevrolet app and 6.8 miles of remaining range. The GOM started reading low at 16 miles of range remaining, so I checked with the My Chevrolet app and it was still indicating SOC at 4%.
Reduced power came on at around 3% SOC.
The Car shows I went a total of 248 miles on 54.6kWh, including 7% climate control use. Again Starting SOC was 87%.
I am now checking to see how long it will take to charge from 2% to 100% on my Chargepoint Home Flex level 2 charger at 7.54kW charging rate. The my Chevrolet app says 10 hours.
