Hoppers tend to be worth only half of the corresponding rider. (Compare the classical values of Rook and Cannon in Xiangqi, showing what it does to require a hop for the captures, and then imagine what would happen if you handicap the non-captures the same way...) The AI guestimates the value basically from counting of moves the piece would have on a 25% filled board, assuming a linear increase of the enemy density with rank, counting captures double, and assuming somewhat above-average placement of the piece. And then applies a modest non-linear correction to account for synergy. The latter would not reorder the values, though. So if it guestimates a non-divergent piece to have a higher value, it means that that piece will in general have more moves under conditions likely to occur in the decisive game phase.
