Does the car remember how it was last charged?

I used a Level 2 charger today to get me enough juice to get me to my destination and back home. When I got home I was at maybe 15% state of charge. So I plugged it in to my 110v outlet as is my usual procedure. The cluster told me that it would take 8 hours to fully charge the car. No way is that correct for a 110v outlet, but it is probably correct for a 220v or a Level 2 charger. So did the car's computer remember that the last charging was done on a Level 2 and use that number? About seven hours later I checked things and it told me I still had 8.5 hours to go which is about right for the 110v outlet. So does it take the computer some time to recognize how the car is being charged?

That's right Len. Its the previous charge cycle that is used as the baseline for the current predictions. We charge 240v at home and 120v at my wife's work. So on work days the prediction is always wrong.

Thanks Blaine. So at some point it realizes what charge cycle is being used and corrects any wrong info.

BTW my coupe that I used yesterday for a hundred mile trip generally at no more than 50 mph charged over night and the expected range this morning shows 90 miles. Been a long time since I've seen that and that was after another long trip.

Thank you for that. That clarifies a long time mystery for me.
