Yes, but if you leave Fritz6 on top it is too inflated compared to human games,
  and dropping hiarcs rating would be a problem as well since it earned its
rating 2573, it seems like the damage is done and you need a separate ratings
list for comps vs human.  I do not think you can just lower the ratings straight
across the board.
