The contrast of the difference in OTB v Corr ratings is highlated by a recent corr champ and SIM :

His OTB rating is 1809 and can befound here : http://www.uschess.org/component/option,com_wrapper/Itemid,181/
A difference over 700 points is quite staggering !
Please sir, do you not see the folly in the continued beating of this dead horse? These ratings have no more in common than his chess rating has with his checkers rating. Further, Elo ratings from different pools have no meaning. What, exactly, is the point you are trying make?
In the long run, we may be heading to a Lake Wobegone of chess, where everyone is a GM!
(At least on line.)
