There is not a statement like this from them Bob, i never nor any other CCC member saw ever one. In contradiction in IE99 something else was said and about older versions of DB there was no unclearity either what depth they got. Also deep blue junior when analyzing at the ICC with kasparov-kramnik was very clear in what depth they searched after a few minutes and what it missed tactically compared to diep, which got 1 ply more, was also real simple to see (that diep version DID have singular extensions btw). Yet you believe that they search 7 ply deeper by adding a few more cpu's, by a statement which was NOT done by Hsu and only emailed to you?
