I have always thought of "average" as being the best of the worst and the worst of the best.  Having said that, I'd agree with the prior comments, each reflecting the various issues folks have encountered.

Thinking about this process recently I have concluded that the current approach, as generally understood, is going to need to change at some point in the near future.  One of the reasons come from a great book I am reading, "The End of Tech Companies" by Rob Thomas.
