That is very helpful. Maybe the "almost stable" regions should have
yellow color in the graph.
How about cyan?

I did some more reading tonight, and from Hand: "the E criteria is
proportional to the steering moment exerted in a normal steady turn", and
small negative E can be compensated for simply by subtle rider correction.
So, I allowed E to go a little negative by their guidelines, and in line
with my touring bike experience.
I also added a fudge-factor for steering K (spring) which can also be
easily provided by the rider. The results of these two are colored cyan in
the chart and agree well with my two bikes.
It would be good to see how the flevo looks with it.
I added some supposedly-stable pythons' config files.
I'm not sure I can do anything more without going back to my original plan,
to do a motion integration code using basic forces. I'll build a bike first...
What might also be viable is a thickly greased bushing instead of a
bearing, like a telescope or camera head, to dampen high speed oscillation,
but allow the legs to make the slower turns. I thought that I had read that
someone had tried a damper of some sort?
