@Federberg, you are a data guy. The amount of time Ramos allowed SW to rant is surely a record in tennis. It is completely the other way around, if he made a mistake (which I don't think he did), is that he was too lenient. What was completely out of line, the point out of the curve, was the player behavior. The outcome (a strong penalty in a major final) is out of the norm because it was generated by behaviour out of the norm (specially in a major final).
I really don't get it... people complain he did not let Serena know that he was not questioning her integrity (sorry, this is childish to an absurd extreme, but ok). But anyone who actually watched the video and listened to what the guy was saying know that he explained it to the player. Now, sorry, if the player misunderstood that for taking the call back.... that is completely on the player. And, yes, Ramos did not hesitate to penalise her a game. Instead, he waited for, what, three minutes? If he had given that penalty right at the beginning of the rant, we could have a discussion. But he simply draw a line. She went too far. If that is not too far, what is? Do we really want that to be acceptable behavior on a tennis match, let alone a final? Sorry, people should be at least honest enough to admit they want a special treatment to a specific player.
By the way, the NYT compiled some numbers about code violations and compared men and women. Interestingly enough people don't mention that. Men get much more code violations in every single category. The total number of violations is much bigger for men than women -- there goes the sexism argument. The only category were women get more violations than men is exactly coaching. But coaching is precisely the one item were you have different regulations for both tours. Coaching violations are in fact at least twice as frequent for women than they are for men -- so there goes the argument that such violations "never happen".
For me, most people complaining about Ramos are so desperate to see sexism/racism everywhere that they pass the point of intellectual dishonesty. Not your case here, your main point seem to come from the fact that you expect a different approach to rule enforcement in a major final (which I disagree with, and Ramos surely disagrees too), and, sexism, in turn, would explain why the letter of the law was strictly followed. But I disagree with that. We can only guess, but I would bet the guy would be much less patient with a man.
