Y!勝率的公式應該是 (勝局數 / 總局數) + (和局數 / 總局數)*0.5 以你的例子而言第七名的勝率是 ( 93 / 171 ) + ( 3 / 171 )*0.5 = 0.552631578947368000 第八名的勝率為 ( 92 / 171 ) + ( 5 / 171 )*0.5 = 0.552631578947368000 基本上兩和就等於一勝故第七、八名的勝率是完全相同的沒有餘數差異因此最終種子序將由第 21 週戰績決定希望有回答到你的問題 :) : 查了rules如下: : If at the end of the season, two or more players in a Head-to-Head League : finish tied in the standings, the following system is used to break the tie: : Overall winning percentage. : Highest winning percentage in Week 21. : Highest winning percentage in Week 20. : Highest winning percentage in Week 19. : Highest winning percentage in Week 18. : Highest winning percentage in Week 17. : Highest winning percentage in Week 16. : Highest winning percentage in Week 15. : Highest winning percentage in Week 14. : Highest winning percentage in Week 13. : Highest winning percentage in Week 12. : [下略] : 應該是先比勝率? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 211.76.173.94
