When you are playing tournaments, regardless of whether its only four matches to the final week, there is still practice sesions, and physical training. On top of that, there is the intensity of playing matches, and the psychology involved in the games that result in the body and mind being under more pressure than normal times when there is no tournament that is going on.
Amelie has to decide what is important. Being #1 for a brief spell or winning majors. If she wins big the ranking will follow, but I have noted that she talks about the ranking, her desire to get there.
With such a fragile physique, her body will not hold through the majors, and after a while that starts being a very lame excuse.
She will never win a major at the way she is going.
Take care of your character. Reputation will sort itself.
