Wow!
I'm blow away by this too. It just doesn't seem logical. gear inches are gear inches. As long as the chainline is the same there shouldn't be any difference in efficiency.
I think miami jim is misinturpreting the book though......the author is trying to make a point about chainlines. he mentions 14T becasue normally that is the 3rd cog from the outside in a cassette and those cogs tend to have straighter chainlines than the smallest cogs (big chainring is more towards center of cassette than the very outside)
