Think of it this way. You have an ICE F-150 that gets 15 mpg and and some other small SUV of your choice that gets 30 mpg, and both of them have the same size gas tank. Call it 10 gallons. If you spent 5 minutes on both filling both gas tanks at the same pump, would you expect both to get the same range because they were filled by the same gas pump for the same amount of time? Of course not. The truck would go 150 miles and the SUV 300 miles. Yet your time spent filling them would be equal. Using your EV charging thought process, the truck got 150 miles/5min and the SUV got 300 miles/5 minutes. Pump and hose that the gas flowed through worked exactly as advertised.

No different for a large brick shaped EV truck vs an aerodynamically optimized EV sedan. Make the assumption that the charger is working normally and the vehicles are under normal conditions. You will deliver the exact same amount of energy in the same time to both vehicles. But that equal amount of energy will only get you 1/2 the distance in the EV truck vs sedan, just like the ICE truck only gets half the distance of the ICE SUV on 1 gallon.
makes total sense

Thank you everyone. I think I have a better understanding on the difference now. I think my goal now is simply to make sure in 10 hours I can recover enough charge to cover my daily commute. ;-)

honestly my goal during the week is simply to maintain the same soc (if i am using the term correctly). so I drive 80 miles a day and I would like to be able to work the week using only the lvl 2 chargers at work.
So that's nominally 40 kWh/da. A 32 A charger will give you 0.9*32*240 = 6.9 kWh/h so 40/6.9 = 5.8 hrs would do

I've had a EV for < 48 hours, so still very much a casual observer to charging discussions. Like you, I would have guessed with level 2 charging the rate to charge the R1T from 45% to 70% would be about the same as the charge rate going from 70% to 95%, but maybe its not for the R1. Just collecting data points. Good luck.
