In this subset of matches, Federer is just a victim of a scoring system where all individual points are not created equal. It means that Federer’s dismal record in these quirky matches, somewhat ironically, is yet another data point in support of the empirically driven conclusion that he is the greatest tennis player ever.

In statistical language, one would say that an underdog must be willing to adopt a strategy whose outcome has a larger-than-average variance.
In tennis, such a go-for-broke strategy would involve hitting aggressive second serves and high-risk/high-reward returns when Federer’s is serving.Simpson’s Paradox is a statistical quirk where seemingly correlated variables are reversed when combined.The application to tennis is nuanced: In tennis, a derivative of Simpson’s Paradox is seen in the small percentage of matches where players win more individual points than their opponent, but lose the overall match.Jim Courier was the only player worse than 50-50 in such matches, with a non-alarming 11-15 record. First, given Federer’s decade-plus time as one of the top ranked players in the world, it is possible that his opponents chose to adopt a high-risk, yet upset-friendly playing style when on the other side of the net as an underdog.Knowing that their normal playing strategy would be unsuccessful against the near-unbeatable Federer, his opponents may have decided to select the optimal strategy for an upset, one described by Brian Skinner in a 2011 When facing a heavily-favored opponent, an underdog must be willing to assume greater-than-average risk.Simpson’s Paradox can happen at the both the game level and point level in tennis.
