:A notable possibility for this value exists for a hand, that may be considered as an "open pinfu".  In other words, it is an open hand, that takes the shape of pinfu.  Naturally, it is not classed as pinfu.  For "ron" values, the default lowest value is set at 1 han and 30 fu.

:[[Chiitoitsu]] is by default worth 2 han and 25 fu.  No other yaku worth 1-han can be set at 25 fu.

* '''20 fu''' (ron)
:A notable possibility for this value exists for a hand, that may be considered as an "open pinfu".  In other words, it is an open hand, that takes the shape of pinfu.  Naturally, it is not classed as pinfu, but it still scores 2 fu for an open pinfu. As a result, for "ron" values, 20 fu is impossible; the lowest value possible value is at 1 han and 30 fu.

Thankfully, the points arrange themselves into particular patterns.  In general, an increase of 1-han effectively doubles the point values for hands.  The doubling may be exact for some patterns and approximate for others.  Usually, the difference is about 100 points or so.

Points for tsumo total exactly or closely to that of the ron values.  When a non-dealer wins by tsumo, then the dealer pays about half the total points.  The other half is split among the other two non-dealers equally.  For some ron values, the total is easily divisible by 4; where non-dealers each pay exactly half of what the dealer pays.  However, some values do not.

For example, 4 han and 30 fu is 11600 and 7700 for dealer ron and non-dealer ron respectively.  The tsumo points are 3900 from each player for the dealer.  Here, the dealer earns 11700 points total from all players.  That's a difference of 100 points from the ron value.  For non-dealers, 2000 points come from the non-dealers, while the dealer pays 3900.  In total, this amounts to 7900 points.  That's a 200 point difference from its corresponding ron value.  The 3900 points itself is roughly half of 7900.
In essence, the total of the tsumo values are either the exact amount of the ron values; or they are within a difference of 100-200 points.
