It would have charged slightly faster if he charged from 5% to 66% (same amount gained) instead of 19% to 80%. Even with the improved slow taper vs the sharp step downs in charge rate in the pre-2020, the 2020's still charge faster at below 50% SOC than they do above 50% so the lower your SOC when you start charging, the faster it charges.
To the OP:
To gain 179 miles on 61% charge gained (around 40ish KW) you must be getting 4.4 to 4.5 miles per kWh... you will not be getting that on a highway road trip. You will be getting somewhere between 3.1 and 3.5 miles per kWh depending on what speed you are running. So on a road trip that 49 min of charging would have given you between 125 and 140 miles of range. When your average Tesla driver gets fed up with how slow their Tesla is charging when it ramps down
to our peak charging rate of 55 KW at 75% SOC and leaves, that shows the amount the Bolt is behind in the charging game. A Model 3 on a V3 Supercharger can gain 180 miles (EPA rated miles, closer to 155 miles at highway speeds) in 15 min vs the 2020 Bolt gaining 179 miles in 49 min when driving at very efficient speeds, or as stated above 140 miles max in real world highway driving...
In real world testing by MotorTrend, the model 3 on a V3 Supercharger can go from 5% to 90% in 46 min... a gain of aprox 220 miles (highway speed miles, 255 miles of EPA range) in 46 min. Looking at your charge, if you had started from a lower SOC you may have gained 180 miles in 45 min, but once again that is at very efficient driving speeds... still a half hour longer than the Tesla Model 3 for the same amount a range gained.
In the real world on the highway the Tesla 3 on V3 can gain aprox 155 miles in 15 min and the 2020 Bolt can gain at best 140 miles in 45 min. Hopefully this is resolved in the new BEV 3 cars.
PS: Not a Bolt hater, I road trip my 2017 Bolt cross country a few times a year... this is probably the reason I want faster charging
