"It can be a very frustrating thing, obviously, and very disappointing. But I guess it's also a good thing - you'd rather play well and go down in a tough one than not put in a good performance, either," Stosur said.
"It doesn't necessarily make it any easier right now, but on the whole I'm playing good tennis. But you want to get those wins."

Stosur's attention has now shifted firmly to Roland-Garros
She leaves on Wednesday for Prague, where she will play in the WTA event there next week, before moving onto the Madrid Open, Italian Open and then to the French Open, which begins on May 23.
"All my training and tournaments leading up is going to have to have that big picture kind of focus towards Roland-Garros, without putting it so high you freak yourself out," she said.
"It's definitely the grand slam where I feel like I can do very well, but you've got to play very good tennis and a few things have got to go your way.
"So much goes into trying to do well at a slam.
"I've got a few tournaments leading up to that, that's the next main focus and then I'd love to do well at Wimbledon, Olympics is in there too - there's so much tennis to be played in the second half of the year, it's absolutely chockas and there's heaps of big events.
"I think it's really important to pace yourself throughout certain weeks when you can because there's not going to be too much rest by the time Wimbledon starts."
