Tim,
I'm sorry if my terminology was confusing. By "VPPmax", I mean the maximum forward position of the Virtual Pivot Point. The VPP varies with TV/TT articulation angle and the VPPmax is the value of VPP when the angle is zero. In your revised example, VPPmax is at 47.1" forward of the center of the rear link.
APP can lie forward of VPP; but I think it is correct to say that APP never lies forward of VPPmax.

P.S. That's another very informative plot. Please keep them coming.
Oops, you're right. I was thinking of VPP for each angle instead of VPPmax which doesn't change. Absolutely, neither APP or VPP are ever greater than VPPmax.
Ron, if you're interested in the Hensley video (either the whole thing or only the test model portion), I can put it on a disc and mail it to you if you want to PM me with a mailing address.
