My research indicates the same and the reason seems to be that there isn't a good way to do this without introducing egg (out-of-round) and taper into each journal. Since I'll be spending a fair amount of time at the track, I'm probably stuck with getting a new crank unfortunately. Just don't want to risk it.
Yes, engines that see rpm and race duty are usually built on the loose side of spec. I have a couple of machine shops around. It would be interesting to see what they would do to get an extra .001
