The short answer - it was suggested that rules be changed for 2014 so CB would count ahead of PTS. This was voted down.
Which is pretty logical. Why should a Round I pick decide a Round II match, when the decision can be made on the Round II match. It is exactly what I say: CB should only be used when there is no way to make decision on the actual round pick.
(I understand that there was a need to insert a new method to avoid decision on ranking, and it was inserted to the end, but that was not the logical place)
