>Accordingly, if we assume that a riichi against which no suji has passed yet has a ryanmen wait, the chance to deal in with the first musuji is a bit more than 5%. It usually won't deal in.
>Sanma only has 12 suji, so under the same assumptions the deal in rate of the first musuji jumps to about 8%.
>Of course, middle tiles that belong to multiple suji are even more dangerous.
