推 jerry771204 : 实在不懂3x岁的小威那年代是竞争对手太弱是不是 02/19 11:28
→ jerry771204 : 她00-10表现反而没那么突出 02/19 11:29
接着再来讨论看看20岁的小威跟30岁的小威到底差别在哪的问题
如果我们用小威两次完成Serena Slam的数据当成小威两段生涯绝对巅峰来做对照

两次澳网夺冠来说
小威在2015的ace/DF比更高 发出近五个ace才只有一次双误
2015的致胜球/失误比也更好 打出1.36个致胜球才只有一次非受迫性失误
2003的时候致胜球甚至比失误少
上网成功率来说 2015比2003的成功率高出5%
我们再做个有趣的换算
(winner-ace) / (UE-DF) = 抽球表现
2003 (215-42)/(247-20) = 173/227 = 0.76
2015 (227-88)/(163-18) = 139/145 = 0.96

2015的ace/DF比略高于2002 一样是致胜球/失误的比率要远高于2002
2015的上网成功率小输2002有3% 但场上的时间多花了近三小时(170分钟)
抽球表现
2002 (191-32)/(304-19) = 159/285 = 0.56

2002跟2015在发球的表现是伯仲之间 都是接近四个ace才一个双误
但致胜球的部分大胜快一倍 上网部分则是2002赢5%
另外场上时间2015多打了两个半小时(153分钟)
抽球表现
2002 (131-41)/(118-10) = 90/108 = 0.83

在美网的状况2002大胜 致胜球和失误的比例则差不多
