Delta 4

Maybe this is how it was done?  ...seems plausible to me.

I'm no expert on this, but from what I've been able to observe, the vast majority of the human race appear to be a Delta 3 model.  I do know one or two people who I suspect of being a Delta 1 or Delta 2.  It seems only a select few have advanced to Delta 4.
