Oh, no, not this again...

The fact is that getting out of the water in the least amount of time should
not be the primary objective.

Do us all a favor go to Kevin Connell's archives and do a search for 80/20
or Bakers Dozen and save us a lot of bandwidth.

If you have any additional questions, come on back and ask.
