Recuperation – short and strong or long and gentle?

I’ve been driving the 500e for 2 months now and I can handle the One-Pedal-Drive well. Meanwhile I also take the foot very late from the accelerator pedal, because I have grasped the strong braking effect of the recuperation. But what is more effective for the energy recovery? Late down the foot from the accelerator pedal, thus short and strong braking/recovery, or yet slowly lift the foot up, thus long and gently braking/recovering? What experiences/opinions do you have? Please don’t discuss here sion about road safety, driving accidents or the like! If you want to, you can make your own thread. Thank you.
