Dunno, Steve - the message "For a more accurate preview..." seems quite a long way from "you need to view at 1:1".
I think Adobe could be a lot more explicit about this, given the recent flurry of similar posts - which is in itself interesting: I'm pretty sure that this "issue" is a recent one, and I seem to recall that in previous releases of Lr, even the view-to-fit previews looked like the eventual output.
In any event I know that I never used to routinely preview at 100%, whereas these days there's a clear need to.
