This would have the desired effect with "QU", since a "U" follows a "Q" in almost all cases. Given the columns: M N Y A E T E the operation would then consist of "which letter will probably follow the M" type decisions, rather than "which pair is most common". Other than that, the algorithm would probably be very similar. Kevin Hunter American Bell houca!kdh
