I am planning to make the statistics for every top tier tournaments. One of the statistic is about the hardest match. But, I am struggling how should I define the hardest match statistically wise. I personally think that the rubber games match is harder than the straight games match. I want to determine the hardest match from the scorelines. Any ideas of how should I determine? I have three cases to be examined. The sample is from Malaysia Masters 2019. Inoue/Kaneko vs Wahyu/Ade 19-21 30-29 21-18 Total scoreline : 70-68 (+2) Nishimoto vs Momota 21-15 14-21 22-20 Total scoreline : 57-56 (+1) Srikanth vs Wong Wing Ki 23-21 8-21 21-18 Total scoreline : 52-60 (-8) The first case has the most points scored. All of the games were tight. As for the third case, the winner produced less score than the loser. How should I look at these?
