The modal choices of DM1 match KT-V4 in 8 or 9 pairs. It depends on whether modal choice does or does not include the knife-edge case where a person chooses either option equally often, as DM1 does in Pair 10. DM13's strict modal choice matches KT-V4 only in four out of 10 gamble pairs. In the literature, many authors would interpret this finding as indicating a poorer performance of KT-V4 for DM13 than for DM1, and an inadequate performance for DM13 overall.
A major complication with the analysis so far is that it ignores the magnitude of the disagreement between KT-V4 and the observed choice frequencies.
