Guestimates based on observations. If you notice @sneak informed me the 1st paragraph of my post was wrong but didn't say anything about the percentages. I have since learned that @sneak is the Lead Developer for Steemit Inc. so I am assuming that means I was wright with my math....or at least close enough he did not find fault with it. Now if @sneak would just remove the flag he put on the post I would be happy!
