This is my messy text log of my trip. Thanks to PlugShare for info for charging.

Trying a different spot on route! BMW Chargepoint in Baton Rouge was open and working at 12:45AM - had 53 rated range when charging started. Charging at 204V at 30 amps = 18 rated miles per hour rate Left with 67 range at 1:40a / 44 map miles remaining / 28F Went 45mph on hwy 61 till I had to go I-10 / 270 pwr 60mph on I-10 East till hotel / 365 Wh/mi Torque limit appears at 39 rated range of 19 map miles Red battery at 18 rated range of 4.5 map miles Torque limited to 160 / 30F Arrived at planned hotel at 2:40a with 12 miles range left. Semi trucks totally blocking EV spots. Had to take car off road into field to get to other side of charger post. One HPWC didn't engage. Tried other and it engaged but at 'half' power (40A) so it says 9.5 hours till full charge but checkout is in 7.5 hours (11a) :/ Hotel let me stay in room till 12p as I got last part of battery charged up. Staff asked me many questions and I told them my suggestions for future customers (I apparently was the first person here that really used the chargers). They also have a Clipper Creek style public charger box back there. Next stop is 208 map miles away. Benson Appliances in Foley, AL Benson Appliances has several flavors of chargers available including a Tesla HPWC. Charged to 244 rated range before leaving 1pm.

Power steady at 335 and then leveled at 305 for bulk of run at 60mph Got to Benson appliances at 4:33p with 14 rated range remaining. Greenville, AL Supercharger is 134 miles from here and I'm at 15 range. So far charger is giving 40 miles of range per hour but it's still ramping up I hope. Full charge says 5.5 hours. Going to find food! Charger was 200V/80A and eventually peaked at 49 mph charge rate so I wasn't able to leave until 8:15p with a rated range of 180 for 134 miles.

Landed at Greenville Supercharger at 10:55p with 10 rated range remaining/ 28F Next supercharger is 101 miles away in Auburn, AL so I'm planning to charge past 185 so I don't have to hobble along as much Leaving supercharger at 11:55p with 215 range 22F / 70mph / less hills / 415 wH Landed at Auburn Supercharger at 1:42a with 70 rated range Leaving Auburn charger at 2:18 with 195 rated range for Decatur charger 114 map miles away. 24F -> 19F 70mph / 375-405 wH Landed at Decatur, AL Supercharger with 39 rated range at 5:10a Left charger at 5:25a with 105 range for a little buffer - 15 mins! Landed at destination around 5:40a. Unloaded car. Plugged in car to wall. I made it! Phew! Now, if I run some summaries for everyone about the rated ranges versus map ranges I come up with an approx % drop of real-world in the cold performance of range.
