Not necessarily more scientific, but I've logged a lot of miles hypermiling.
First, we normally buy a nice car to enjoy it. So that comes first. Drive it the way that makes driving pleasant for you.
Now about hypermiling. The higher kW load you put on the electrics in either direction the more kWh is consumed as heat and the more cooling is used. A fast charge or discharge loses more power per mile. On paper it would seem blasting off from 0 to 50 mph then max regen back to 0 would cover distance at a faster average speed, hence save power, but I've seen the opposite. It's not huge like a gas car, but it's there.
So keeping the rate of acceleration and deceleration low improves range. For many drivers, it's easier to keep the regen peak down by using low regen augmented by the brake only if necessary. This also keeps you looking further ahead, so you decel earlier and accel more gradual.
The brake pedal regens at first, until you run out of regen capacity, then it uses the friction brakes. The friction brakes appear to always be in use at very low speed, say under 4 mph, so try to avoid complete stops.
Note: You will hear the exact opposite, and you will hear it doesn't make a difference. I base this on trying to achieve maximum miles per kWh in a car with a smaller battery that I can run empty since it has a gasoline generator should I run short. And when I tried to hypermile the I-Pace, I saw a similar effect, but I can't run it 'dry' too often.
