 *When the dealer goes out by ron, the discarding player pays the winner 6 × basic points.
-Each value to be paid is rounded up to the nearest 100.
+Each value to be paid is rounded up to the nearest 100. Because of how this rounding works, a tsumo win may result in a few hundred more points than a ron of the same value. (For example, a 1 han 30 fu hand scores 240 basic points. Without rounding, a ron would score 960 points, and a tsumo would also score 240+240+460 = 960 points. As each individual player's payment is rounded, ron scores 1000, and tsumo scores 300+300+500 = 1100.)
-The numbers for a ron payment are obtained by having the ronned player pay every other players points. Because rounding is done after this reassignment of points, it is sometimes the case that a win by tsumo is worth a few hundred more points than a win by ron.
+In other words, when hand wins by ron, the ronned player pays 100% of the hand's value. When a hand wins by tsumo, each player splits the payment evenly (with the dealer paying double).
