Male players were slapped with 1,517 fines compared to 535 fines for females according to data compiled by officials at Grand Slam tournaments for the period covering 1998 to 2018.
Apart from the possibility that the match may not have been over at the time, her behaviour can not be condoned.
These questions persist as debate over controversy that marred the Open finale won by Japanese Naomi Osaka continued a week after it happened.
"I say it with sadness, but he is an umpire who scrutinises me more and who fixates on me more", Nadal said after the match.
"Me, as a woman, take a lot of warnings. I'm so angry that my anger is going to manifest as tears, and everyone around will call me hysterical, and then I'll start shooting rage-lasers out of my eyes until I'm sitting alone on a pile of smoking rubble".
The second variable comes a lot closer to Williams' actual complaint.
"Do you know how many other men do things that are much worse than that?" They think differently. And men don't really understand women.
Boston Celtics' Jabari Bird charged with attacking his girlfriend
Bird was ordered to not have any contact with the alleged victim or any witnesses, and he must stay away from her college. Elizabeth's Hospital reportedly delayed his arraignment originally scheduled for Monday.
Williams accused Ramos of sexism during the US Open final in NY, branding him a "thief" and a "liar" after he issued her with a series of code violations. The warning incensed Williams, not only because coaching hand gestures have become so common in the modern era of tennis and nearly always go unpunished, but especially because it called her character into question.
"Maybe men should just referee men's matches because they know how men think".
None of this lets Williams off the hook. Instead of trying to de-escalate the tension, Mr. Ramos cited her for "verbal abuse", docking her a whole game. Williams accused Ramos of sexism, pointing out that men are rarely called out for such outbursts.
However, the data alone doesn't negate Williams' broader challenge either, even if it does make it more hard to establish.
"We can not measure ourselves by what we think we should also be able to get away with".
If, in fact, the guys are treated with a different measuring stick for the same transgressions, this needs to be thoroughly examined and must be fixed.
When one remembers, among other things, Serena's outbursts in 2009 against Kim Clijsters, and in 2011 in the final against Samantha Stosur when she was losing, however, it appeared that her behaviour stems from a belief that she has a right to win, and that she can not - or should not - lose.
And those involved in helping women continue to battle to get more awareness of the issue, and indeed funding.
