Brent-
Your explanation makes sense to me. .050" is out of spec, but let's put this another way, you engine is not toast! There's a guy here in Michigan who let his 90S4 go totaly all the way to the point where the pistons ground into the block!
Poor bastard. 
From his perspective, you're in great shape! Taking a line from Home Depot, "You can do it. We can help!"

Do you still have the accessory belts on under tension on the front pulley? if so, they may have some centering force on the crank, pulling it in to a favourite sweet spot when releasing the pry bar.
As a solo DIY type, when measuring the float, I have used a web strap hooked to the top cross brace and drawn down across the front pulley to a cozy spot under the bell housing. It's quite easy to force the crank forwards to get that measure .... and pull on the strap to get the rear crank position when measuring at the flywheel. As mentioned easlier, the dial gauge is best .. but the clamped nut, bolt & feeler gauge also works.

Garth, I think that you hit the nail on the head! Of coarse........ I never thought of it. Yes, I still have three belts on it thanks! Maybe, someone needs to add that to their diagnostic procedure so people don't measure it and think it's okay. I would have thought mine was if I hadn't rechecked it with Pizza.

Brent, sorry to hear that -- but it's better to be sure, eh? Many issues with 928's disappear with regular use... not this one. 
Andrew --
Larry, pulling the pan is a hard road to travel, especially since it seems the engine has to come out anyway. Pulling the rack, crossmember, etc is part of pulling the pan in situ -- along with an alignment. There is no sense in taking stuff apart on this scale if it can't really lead to a cure, IMHO.
