The Chinese chess paper (section V.B) reports that, in a match between trained EVAL0 versions, the one with tapered eval (which, in that case, interpolated between the opening and the endgame) beat the one without convincingly, with a 62.75% winrate, but of course, the tapering coefficient doesn't have to only depend on the phase of the game, and even further gains seem possible if there are >2 competing scores like in Winter (which currently has 4, as regulated by the kNumClusters constant).

Just to be clear, Rodent IV code compares competing piece/square table scores which already take into account game phase. Winter does something else (probably something great).
