Exactly that.
Fastned publish charge curves for various cars they've tested. Here's their graph for the Leaf:

You can see how the 30 keeps its charge rate up to 80, but the 24 drops as it goes. The Leaf 40 might well benefit from the same 65% strategy, giving it about 85 miles between "hops" (but of course rapidgate is another thing there - although I think that using this strategy might reduce battery heating).
It's easy to think about for a journey of infinite length, but real-world effects mean things are a bit different. There's the time overhead of pulling off the road to wherever the charger is, faffing with apps etc to get the charge going (Tesla saves the user 1-3 minutes of charging time here by being a simple plug'n'go, without farting about trying to remember you CVC code etc) which makes multiple stops more lossy. There's the simple matter of we don't go on journeys of infinite length - You need to look at the journey that you are doing and figure out what the correct strategy for that journey is.
In the example I gave of my 140 mile journey (from my workplace where I have charging available to my mother's house where I have charging available), it could theoretically be done in 1 stop in the Leaf 24 in summer by being very very careful, but the charging time to do so would be 20-30 minutes longer than a 2 stop. For a Leaf 30 the same journey is a solid 1 stop, and for the 3SR+ it's a no stop required (other than human endurance!). One thing about the way I did it was the stop at 62 miles - the next charger along the route was another 17 miles on, so I wouldn't make that gap reliably or without stress.
So yes, it's about understanding the charge curve and how it interacts with your journey and where chargers are available along that journey. Assuming that your e2008 is the same in this regard as an e208, then:
Has anyone charged an e-208 on a 150kW charger? How was...
Again, this suggests 65% as the time to move on. Using 5-65% on the e2008 should give you about 100 miles between charge stops, and 35-40 minute stops on 50kW chargers, 25 minutes on 100kW+ charger.
Edit: Of course, the real-world is that if your charge stop is 120 miles from your destination then obviously you just hang on a bit longer to 75% or so. If it's 150 miles then probably better to stop again for a 10 minute splash closer to the destination.
