Decision rules proposed by Krapohl (2005) that begin with asymmetric cutting scores for 7-position scoring: if the grand sum of scores is -6 or lower, the call is DI; if the grand sum of all scores is +4 or greater, the call is NDI. In those cases where the grand sums ranged from -5 to +3, the sub-totals (Spot Scores) are evaluated. For those cases, if a single relevant question has a sub-total of -3 or below, the decision is DI. All other cases are called Inconclusive. See: Krapohl (2005); Krapohl & Cushman (2006).
