Correlations, correlations, correlations. It all boils down to 
correlations. Not the fact that there are correlations, but that they 
are very, very different from one clue to the next. All these mailman 
clues are correlated. And by not downweighting them, we're blinding the 
procedure to the other clues that do not come by the dozens...
