Most models from other vendors don't have Ikf at all. So the models

It isn't how good the models are that is bugging me; it's the unreality
of giving the parameters to so many significant figures. I suspect that
if tolerances were added we would see:

IKF = 392.8188163 +/-1%,

so that only a value of 393 is justified, given a range of 388.9 to
396.7. But even if the tolerance is 0.1%, the same argument applies; to
state 10 figures is meaningless.

But it's hardly a matter of outstanding global importance.
