At 4a 7a these two positions show extremely close results with regards to games won and gammons won by both sides. However one is a correct cube and in the the other it is a big blunder. How can the ND equity being only .01 higher and the cubeless equity after DT being .05 higher give a DT equity which is .16 higher?
