How to Total the Fu
Base fu＋Closed ron＋Tsumo＋Sets＋Pair＋Wait= Total→ Round up to the nearest 10
Example (closed tsumo, closed triplet of simples, two-sided wait)
Base 20＋Tsumo 2＋Closed triplet (simples) 4＋Pair 0＋Two-sided 0＝ 26→30 fu
* An open hand won by ron is rounded up to 30 fu even if the total is under 30 (open pinfu shape).
