It might be best just to let Jack predict from his present position..As to his "ear" from a geologist, Jim B and Jack were close friends socially and ran the original earthquake hotline at a 900 number in NorCal. I see some potential in what Jack does. And so does Diane Pope. She might be the one to ask about the squaring deal. Diane is a firm believer and she has an interesting track record, skewed only by some personal beliefs.
