In making determinations, the arbitrator shall give due weight to each relevant factor. All of the above factors shall be presumed relevant. If any factor is found not to be relevant, the arbitrator shall detail in the arbitrator's findings the specific reason why that factor is not judged relevant in arriving at the arbitrator's determination. With the exception of paragraph (d)(6) of this section, no single factor in this subsection, shall be dispositive.
