Of course, we're all kind of guessing here because that isn't exactly a well-written spec...
That's a pretty good assessment, and I appreciate being granted a little latitude in my interpretation thereof. About the best I could do was guess, and then do a better job than the OP of documenting the criteria I came up with. :) When posts like this come up I have to make a decision whether to take a stab at trying to guess at a more refined specification, or to post a node seeking clarification (which often never comes), or to just let the question go and continue about the work that the question was distracting me from in the first place.
Sometimes what tips the scales for me is if I find a little amusement in the diversion of coming up with a solution to the specification that I invented by venturing a guess. My hope is that it's also helpful.
