Quite First_Principal that was my experience too, was told about 5hrs as a ballpark figure but in reality it took about 7hrs before the actual signature. As Chuck and others say, it is frustrating but the answer to 'how long does it take?' really does have a 'how long is a piece of string?' answer.
I commented on the 10hrs suggested in the book because a lot of clubs state (like mine for example) on their websites 'five hours training' which is often unrealistic.
