Well, if that's the case, maybe Petra should make changes to her team because that is not a long-term answer.
We would only hope Lupo.
Cause the way Petra's going now, she'll always be inconsistent, until the few stretches she'll find her game and confidence, then play well.
Nonetheless, it will be boom and bust until Petra opens her eyes and/or finds better team members. Cause currently, she's drastically worse than she's been to start the season--the past three years. Not even close!
Petra's going backwards and that's troubling. And it's not like she can't play better. She can. It's just that her level of dedication, confidence and execution, will not allow her to place consistently high results, even compared to the first 3/4 of her 2012.
As you indicated: It's up to her (but easier said than done, unfortunately in her case)!!!!!
