In making determinations, the binding interest 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 binding interest arbitrator shall detail in the binding interest arbitrator's findings the specific reason why that factor is not judged relevant in arriving at the binding interest arbitrator's determination. With the exception of paragraph (6) of this subsection, no single factor in this subsection, shall be dispositrive.
