Just every time you let off the accelerator. You have to judge whether the regen gained versus the speed lost is worth it. Kers 3 is too aggressive out of town so I generally drive in Kers 2, I live/work in a very hilly area so that works best for me.
I'm one of those, a fiddler.
There is no right or wrong way, it's whatever suits yourself and you feel good with.
That's more or less what I do now . It was a lot easier on the last car ( Hyundai Ioniq ) which had paddles on the steering column . I do miss that but it's no big thingI'm one of those, a fiddler.
Maybe because on the pre-facelift as there is no having to go into the infotainment for anything, KERS/MODE are the only things I can fiddle with, so I do. I find feathering the throttle though in K3 not so good on gentle downhill slopes as switching to 1 and coasting, then practicing the art of gradually increasing to 2 and then 3 as I need to come to a halt at the bottom.
Oh I do like a game.
The KERS 1 seems a little more forgiving on highways. I mostly use 3 and a little sensivity on the accelerator-panel in cities and heavy traffic on highways.
I have found that if for instance you have the cruise control set on 40mph and you accelerate up above that set speed (eg. up to 60mph) and take your foot off the accelerator it will coast with no regen, virtually free wheeling until your speed drops to the set cruise control speed which can be quite nice going down hill.

Absolutely correct, the accelerator is not an on / off switch, good anticipation and observations to minimise change of speed are key to good fuel consumption. My i3 I have managed an average over 5 years of 5.4 Miles / kWh, my previous car to the i3 a 4.4 litre TDV8 Range Rover I used to manage 43 mpg on a regular 220 mile trip to Bournemoth with the exact same techniques.
My ZS does. Try dropping the kers down a level as you're applying a very light acceleration, you'll feel the car surge forward very slightly.
EV power-trains are complex computer-controlled servo systems. Changing a major parameter when in motion is bound to cause a noticable hiccup as the servo system re-adjusts. It certainly doesn't follow that lower regen settings are somehow more efficient. They're not.
It is possible that efficiency gains are witnessed if the driver is pumping the accelerator to maintain a speed rather than slightly more or slightly less. I have a friend that drives like this, it nearly drives me crazy. The control system I agree with you 100%, nothing to be gained by the KERS lower settings, in fact, quite the opposite.
