Assuming you are playing against experienced players, sotogawa is a bit less safe than [[suji]], but still on a comparable level to suji. A tile that is affected by both sotogawa and suji (e.g. a 2 after both 3 and 5 are discarded) is safer than a tile that is one or the other.

The concept of [[matagi suji]] is the main reason why sotogawa is effective. Matagi suji states that an opponent is less likely to cut a 3 from "233" or "344". So, if they cut a 3, it is less likely for them to have "23" (waiting on 1-4) or "34" (2-5) remaining; this makes 1-4 and 2-5 safer. Of those, 1 and 2 are especially safe, while 4 and 5 are not safe due to the existence of "56" and "67" ryanmen. Thus if 3 is discarded, 1 and 2 are safer.

Generally, "early discards" are the first six discards of the game. If a player declares riichi early, then the sotogawa of the riichi declaration tile become more dangerous instead of less dangerous.

Sotogawa is less effective against new players, since this theory relies on players having strong [[tile efficiency]].
