High regeneration vs Low

Seems to me that when highway driving (NOT city driving) it shouldn't make much difference which mode you're in. My (admittedly weak) grasp of physics tells me that if a certain mass has to be brought to a stop in a certain place, high regeneration will require power until close to the stopping point, then lots of regeneration will occur over a short time when the right foot lifts.

With low regeneration you take your foot of the "gas" earlier, so you have low regeneration but for a longer time. My guess is the result should be the same amount of juice fed back to the battery.

This argument assumes no use of the brakes, of course, until the stop is made. And it would not apply in stop and go traffic where you can't take time to anticipate a stop.

Anyone with a better scientific background care to comment?

I prefer the Low regen because the car coasts a bit more and the break lights don't come on since there isn't sudden deceleration. High or Low really depends on how you like the car to feel. As JSimon7777 says, there is a safety factor with high regen. If you are trying to achieve best mileage, I've found I get better mileage with low regen.
Thanks for all your responses. So far I've found that (a) high regeneration in the city is wonderful - one pedal driving is great and (b) on the highway low rejoin feels much better.
What I'd like is if the short-cut button on the left side of the steering wheel could be set to change the regeneration mode without having to go into My EV/ Set Up in the menu. Alas, it appears this is not one of the choices you can make.
Yes it would be nice to have a short cut so you don't have to take your eyes off the road. Even with being able to customize your main display and put myEv on the front, you still go a couple clicks deep. This is one time that a button or paddle or a different programmable widget on the InControl would be nice to have.
