Freewheel vs. recuperation vs. automatic recuperation

If I have observed and understood it correctly, there are three ways to handle the consumption as efficiently as possible, but which is the most useful one? Freewheel is practically standard. When I walk from the gas it rolls there or sails. I only get energy back when I brake. The recuperation via the paddles on the steering wheel in two stages leads to an energy recovery as soon as I walk from the gas. Resistance comes and the car slows down. When I turn to automatic recuperation in the MMI, it detects – exemplary – local entrances. When I walk from the gas, it automatically slows down to the permitted speed plus the tolerance I have chosen (at my place 60 km/h) and passes into the free run. But also on motorways, it detects limits and brings resistance to energy generation. Standard in comfort is the free run. On dynamics, I have the first stage of the recuperatio n automatically in it. I always have to reactivate the automatic recuperation even during the ride when I change the program. Is this all so properly summarized? And what would be the optimal setting? Does it make more sense to choose a lot of freewheeling or sailing or rather to be constantly on the gas and recuperation when you go from the same or yet the automatic?
