Well, you're certainly right!  You've yet again managed to find another awful edge case in the SoI transition code.  Congrats. Notice that when you first hit the Kerbin SoI you actually have an eccentric (not hyperbolic) orbit?  This is because I have some code that actually searches for SoI transitions in a few kilometers into the SoI in order to help mitigate those funny cases where you bounce between SoIs because you're right on the bleeding edge.  Normally it's too small to matter, but
