One thing worth noting, though, is that Sheldon's chart assumes the road/double crank would be using a road/double bottom bracket spindle. In my experience, the use of a spindle meant for a track/single crankset would place the chainring (when mounted on the outside) in the correct position - or close to it.

In such a case, though, it's likely that you would have to grind off the mounting lugs for the inner chainring. Otherwise, they will make contact with the chainstay.
