This is identical to your sim #1, except the secondary is at 200 AU instead of 750 AU. All other values are the same.
The formulas give:
Pkoz=486265 years
emax = .94
Again, the simulation is right on the money. But I tried your sim at secondary sma=750 AU and got the same results you got... Insignificant delta eccentricity, and a linear inclination advancment. It almost seems as if the Kozai Mechanism turns off at a certain distance. Maybe that makes sense. It turns off completely at inclinations <~35 degrees.
I ran this at time step 16K, which was too fast once the planet's ecc approached 0.94, so I don't trust the graph beyond what's shown.
So at what point between 200 AU and 750 AU does the Kozai Mechanism simply stop working as advertised?

Me too. Despite all the forumlas in all the papers, I think there's still stuff to discover about the Kozai Mechanism.
I'll try a 400 AU run and see what happens.
