I'd think that the success rate on smooth (or any kind of) jazz would be on the low end of the curve due to the extensions, suspensions, inversions, and generally close voicings used therein.
That said, I've been pressing Sher Music to put out a smooth jazz real book for some time now. I've got a bunch of arrangments of my own, but that computer took a dump a while ago and I haven't been interested in resurrecting it. Guess I'll have to start over.
