I just don't like swimming at all so I'm not bothered. Why care about a sport that hasn't got even 30 minutes of my viewing since 2014 lol. But I do like finswimming , obstacle swimming, and few finals sessions of para swimming in major events.
Athletics is another shocker just initial and final graphics after long time or some times not at all , no live timing of race which is bad.
Tennis, Golf, 3X3, Wushu, Pencak Silat, Futsal , Football, Volleyball ,Snooker and Billiards , DanceSport look perfect to watch.
