There s nothing deceitful about comparing WSX with Marin. You see it that way because you believe CHN players can do no wrong and WSX is a CHN player.Marin's behaviour in that match was totally unfathomable and can't be measured with WSX here - it is pretty deceitful of you to try to compare the 2.
Marin was at her 'ugliest' form of her career at that time - behaving like a bad loser after time she concedes a point. She would also scream loudly at her opponent (which is her trademark but worse); turn her back and walk to the back of the court instead of returning the shuttle properly within a reasonable timeframe. She would argue profusely with the umpire many times; displaying considerable disrespect.
On top of that, she would make rude and angry faces/body language at her opponent which was quite shocking to see on TV - quite sure the umpire caught that too. Never seen anything quite like that for a while I remembered saying to myself.
That match did changed her somewhat and she has improved seemingly; much to her credit.
Now let me show how WSX and Marin are similar and different:
1) Both yell during matches more to offend and disturb real opponents than to release tension. It s a tricky weapon because when they start to yell less, the alert opponent will know fatigue has set in. Energy is required to produce sound and they reckoned they can t afford to waste energy on a peripheral vocal weapon. Anyone else notice how WSX minimized sound energy usage against Nozomi?
2) Overall, WSX is a much, much gentler version of Marin in the yelling department. However , Marin is better than WSX in one way. Her serve routine is quick; WSX s serve ritual delays play when she uses it for thinking and recovery time. It s a real pain to watch her serve courtside.
I believe you miss the point about the red card. It s not the intensity of misconduct that matters. When Nozomi was ready and WSX constantly delayed play despite constant warning ( regardless of to WSX or both), the misconduct threshold s breached, hence the red card. As you said, Marin is better behaved now, probably because of the red card effect. Hopefully WSX learns not to give umpires any more tests in future.
