Interesting number crunching agrossfarm.  I have seen some really low numbers and some really high and never been able to figure out why they weren't in the middle range (of mid-3s to mid-4s) which is where I think a lot of people see this landing.  Perhaps the high were coming from people forgetting to remove debt and low was from people subtracting debt from a mid-range debt which was calculated either using debt, or a method that did not look at assets v. debts (earnings, etc).  Just a thought.
