Jo Konta has admitted that an element of burnout was involved in the late season slide that saw her miss out again on the women's equivalent of this week' s ATP Finals.
The British No 1 was again edged out on the elite field of eight in Singapore by just one place, having looked a near certainty before losing four straight matches, beginning at the US Open.
Despite having had what was, overall, a highly creditable season in finishing ninth, she then split with coach Wim Fissette.

In the past month she has had a break spent largely at home in London to reflect on a year whose highlights included making the Wimbledon semi-finals, and winning the prestigious Miami Open.
The unforeseen subsidence may have been a reaction to the strains of the grass court season, which turned out to be the high water mark.
'There's always going to be multiple factors and I think it was combination of burning out a little bit and not finding the right balance of rest and training,' she told Sportsmail.
'It's always an accumulation of things - this was a season when I experienced a lot of things I hadn't done before.
'It was my first season starting as a top 10 player and with that comes more responsibility and more strains on your time and that's an adaptation process for anyone. I felt I did the best I could and next season I will try and do better with handling everything.

'It was the first time I had really gone through something like that and I don't want to read into it anything more than I have to. It's a great thing from me to learn from.
'I'm trying to take my whole season as a whole, looking at the good and the difficult periods.'
Earlier accomplishments faded into the memory as a late surge from France's Caroline Garcia saw her grab the last available spot for Singapore, denying Konta becoming the first British player in 33 years to make the event.
