One of the significant safety issues with the sectrorisation is RETRANSMISSION where one controller has more than one VHF outlet and the associated sector area linked together. In some circumstances a transmission (broadcast) can be heard 500 or more miles away if within range of an outlet. This in fact causes artificial frequency congestion. The sectors are primarily designed along air routes, but the grouping of sectors together is a staff management issue. There is little or no consideration given for lower level ops in the design of sector boundaries.
