I guess the solution to that is only win big hands, but that's its own problem :)
- 25 fu hand (chiitoitsu) 16 / 32 / 64
- 30 fu hands: 10 / 20 / 39 / 58
- 40 fu hands (especially toitoi, but also some others with koutsu's) 13 / 26 / 52
As long as you don't have any kans (and you mostly shouldn't call those), the others are a rounding error.
