The disparity is surprising - candidate 19 scored highly for most of you - two at #1 - but one board member had them at #19. Candidate 2 had four #1s and a #19. Have you discussed why this might be? Maybe negative (or positive) bias towards a type of candidate? Lack of clarity or agreement about what you needed? Something else? Have you measured whether one (or more) board member was significantly out-of-step with the end result?
