Britain's Katie Boulter admits she feels she has to "choose between my physical health and my world standing" as the race carries on for a place in next January's Australian Open primary competition.
While the regular WTA Tour competitive period is finished, there are still standing points to be won in Chile, regional locations, multiple sites and international tournaments.
The female participant roster for the first Grand Slam of the forthcoming season will be based on the world rankings of the December cutoff, which could cause a challenging situation for competitors approaching the cut.
Ex- British leading competitor Boulter suffered an groin injury in her final event of the year in Asian venues last month, and is now evaluating whether to play in the WTA 125 development competition in French locations, France, in the opening days of December.
Boulter's current physical issue, and the fact she would need to win at least several wins in the French tournament to enhance her standing, means she may probably eventually not participating.
In contrast, male athletes are not facing the same situation, as for the premier occasion the men's Australian Open entry list will be drawn up from current week's rankings, which is the ATP's official season-concluding position determination.
The modification is designed to preventing competitors from seeking position points during what is fundamentally the rest interval.
This period has been a challenging one for Boulter.
She secured just 14 professional major tournament games and lately separated with coach Biljana Veselinovic after a extended working relationship in which she won three WTA titles.
"Biljana is an exceptional instructor, and an exceptionally good human as well, which creates situations very difficult," Boulter said.
The search for a new trainer is actively progressing, seeking someone who has high-level expertise as Boulter still believes she can be a top-20 competitor.
"Progressing with a new coach, one thing I'm absolutely certain on is that they are going to be a professional who has considerable experience in how to advance to the very top level of this game," she explained.
"I've been placed as high as 23 and I am confident I can climb back to that position. I am not convinced my standard has disappeared, I believe the steadiness should enhance.
"My objective is not to be ranked fifty, forty, thirty, 20 - we've been there. The objective is to be among 20."
