A case of over-confidence cost Singapore swimmer Tao Li a place in the 100m butterfly final at the Fina World Cup meet on Tuesday.
It was the first time since the series came to the Republic in 2007 that she failed to make the final on home soil.
The butterfly specialist clocked 58.97sec in the heats, missing a place in the eight-woman final by 0.01sec. It was a significant 1.87sec slower than her silver-medal finish (57.10) in the Doha leg last month and 2.69sec off her personal best of 56.28.
All this because of poor judgement.
"By her own admission, she misjudged it very badly," said national coach Ian Turner.
"On the way in, she told me, '58.9 will get me in the final' and I said to her, '57.9 will get you in the final'.
"She went 58.9 and you know the result."
Asked if he was disappointed that Tao did not heed his advice, Turner replied: "I'm disappointed she didn't make the final, but that's swimming.
"When you've got hundredths of seconds, this is just one of those unfortunate situations that can happen to any athlete anywhere."
In the end, Singapore's swim queen could only watch in disappointment as Katinka Hosszu clinched the gold in 56.58.
