Quite a few times in this year's US Open, we saw players seem genuinely surprised when Hawk-Eye called a ball in. Of course, an extreme case of this is Jelena Ostapenko who does this in every match of hers. Perhaps that is excessive - but is there a grain of truth in her skepticism? We find players often questioning the 'ball is in' call than the 'ball is out' call of Hawk Eye. That makes me question its set up. Statistically, there are two types of errors - Type 1 Error (false positives) and Type 2 Error (false negatives). Perhaps the calibrators have decided that a false negative is more 'costly'. Hence the line-calling system is more forgiving. Secondly, they should call out that the picture that comes up on the screen showing where the ball bounced, is not reality; it is not a photograph but a modelled simulation. So that is not necessarily truth.
My question is this - given the above scenario, does it favour players who go for the lines? They may get a call or two to their advantage which can swing a match.
