What does gender equality as a universal value mean in practice? Where’s the boundary between equality of opportunity and outcome? Who gets to draw, adjudicate and enforce that boundary?

I recently watched two quarter-final matches in the Australian Open. The three-set Ash Barty-Karolina Muchova match involved 24 games over 1h:57m. The 52 games in the five-set Stefanos Tsitsipas-Rafael Nadal match lasted 4h:5m.
