※ 引述《nomofan (新手老爹)》之銘言：
: W-L-T Pct GB W021
: *1. 110-58-3 .652 - 5-4-0
: *2. 107-61-3 .635 3.0 8-1-0
: *3. 103-66-2 .608 7.5 5-4-0
: *4. 102-66-3 .605 8.0 5-4-0
: *5. 100-66-5 .599 9.0 7-2-0
: *6. 97-73-1 .570 14.0 2-7-0
: *7. 93-75-3 .553 17.0 5-4-0
: *8. 92-74-5 .553 17.0 4-5-0
: rank7 and rank8無勝差, 但勝率應該是有差的
: 93-75 -> 0.5535714
: 92-74 -> 0.5542168
: 但92-74那位反而是rank8?
: 勝率應該是0.554, 但yahoo算0.553
: 是yahoo的勝率算法不是92/(92+74) ?
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:

: 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.

: [下略]
: 應該是先比勝率?
