[Under Pressure in Service Game 2019] (Data: @atptour Stats Leader Board for
past 52-weeks) #atp #NittoATPFinals
One can compare Break Points Saved (BPS) vs average Service Points Won
(SPW=p*s1+(1-p)*s2) to see the service performance under pressure.
- Federer, Nadal and Berrettini exhibit the same performance under pressure
(i.e. BPS=SPW).
- Djokovic, Tsitsipas, Thiem, Medvedev and A.Zverev are -5% performant
when clutch (BPS<SPW).
- PCB, Verdasco, Wawrinka, Simon et al. are strong when clutch (BPS>SPW).
- Federer, Nadal and Berrettini在被破發壓力下發球表現不受影響
- Djokovic, Tsitsipas, Thiem, Medvedev and A.Zverev則是略低於正常表現
- PCB, Verdasco, Wawrinka, Simon 等在關鍵時刻發球優於平時

[Under Pressure in Return Game 2019] (Data: @atptour Stats Leader Board for
past 52-weeks) #atp #NittoATPFinals
One can compare Break Points Converted (BPC) vs average Return Points Won
(RPW=q*rＱ+(1-q)*r2) to see the return performance under pressure.
Average q=62.15% used.
※對手一發進球率以ATP男子選手平均一發進球率62.15%作假設。
- Very strong perform. by Djokovic for BP conversion (BPC>RPW by +7.4%)
- Followed by Medvedev, Federer, Thiem, Berrettini and Nadal (BPC>RPW by +2~3%)
- Same or worse performance by Tistsipas and A.Zverev (BPC≒RｐW)
- Very strong perform. by Kyrgios, Jarry, Ruud et al.
- Djokovic破發點轉換率比發球得分率還高7.4%
- Medvedev, Federer, Thiem, Berrettini and Nadal 等則約高2~3%
- Tistsipas and A.Zverev 則是差不多
