Britain's Katie Boulter says she feels she has to "choose between my body and my ranking" as the race carries on for a place in January's Australian Open main draw.
While the regular WTA Tour tournament schedule is completed, there are still position points to be won in Chile, regional locations, multiple sites and European destinations.
The women's competitor lineup for the initial Grand Slam of the upcoming season will be determined by the international positions of 8 December, which could present a challenging situation for athletes approaching the cut.
Ex- British top-ranked player Boulter experienced an hip muscle in her final event of the year in Asian venues last timeframe, and is now considering whether to play in the WTA 125 development competition in Angers, the European nation, in the first week of December.
The athlete's current physical issue, and the reality she would need to win at least several wins in the European event to boost her position, means she may probably end up not playing.
In contrast, men's competitors are not facing the same dilemma, as for the initial instance the male Australian Open entry list will be created from this week's positions, which is the ATP's standard year-end standing calculation.
The modification is intended to preventing players from chasing position points during what is basically the off-season.
This year has been a challenging one for Boulter.
She won only 14 elite major tournament games and lately split with instructor Biljana Veselinovic after a three-year working relationship in which she captured several WTA victories.
"Biljana is an incredible trainer, and an remarkably good person as well, which produces circumstances very difficult," Boulter said.
The pursuit for a different trainer is well under way, seeking someone who has high-level background as Boulter continues to think she can be a top-20 player.
"Moving ahead with a new coach, a key aspect I'm absolutely certain on is that they are going to be someone who has considerable expertise in how to advance to the highest echelon of this sport," she stated.
"I've been positioned as elevated as 23 and I am confident I can climb back to that position. I don't believe my standard has gone anywhere, I think the steadiness must improve.
"My aim is not merely to be placed fifty, forty, 30, twenty - we've achieved that. The aim is to be inside the top twenty."
