Miley is one of few on the British team to have chosen to compete at the both the European and World Short Course Championships over the past month and she's reaping the rewards of doing so.
The 23-year-old won a gold in two silvers at the Europeans in Chartres and began her campaign in Turkey by claiming the 400m medley title in a new championship record of 4:23.14minutes.
An agonising fourth in the 800m freestyle followed but it did not put the diminutive Scot off as she raced to bronze in the 200m medley after qualifying for the final in fourth.
Outside the medal positions at the 50m, 100m and 150m marks, it was the final freestyle leg that saw Miley break into the top three and take Britain's fourth medal in Istanbul in 2:07.12.
Double Olympic champion Ye Shiwen, who Miley beat to gold in the 400m, was not to be denied this time and won in a new championship record of 2:04.64 with Katinka Hosszu 0.08seconds behind.
And Miley could not hide her delight at collecting her second medal in Turkey; believing she would only be good enough for fourth, where she was placed after the heats, at best.
"I'm so chuffed to come away with a medal there," said Miley. "That was probably going to be one of the hardest races here, I thought maybe I'd be fourth at the best, maybe fifth or sixth.
"I was hoping to do the same time I did at Euros because that felt absolutely amazing. But I cannot knock getting a sneaky bronze, it's better than nothing.
"I've been trying to work on my backend speed. Ye Shiwen can do it so it's something we've been trying to strive for to show it's possible to come back really, really strong.
"It's just a matter of how well you pace the front end. Those girls go out so hard and it's a matter of hanging on for dear life and that's what I did."
Miley was joined in the final by fellow Brit Sophie Allen who placed seventh in 2:09.16 while the other British finalists on the night, the women's 4x100m freestyle relay team, were eighth.
Fran Halsall, Rebecca Turner, Lizzie Simmonds and Eleanor Faulkner touched home in 3:38.23 as America won gold ahead of the Australian and Danish quartets in 3:31.01.
Former housemates Halsall and Simmonds were among four Brits in semi-final action also, all female, with the latter the only one to miss out on a place in a final on the final night.
Simmonds was fourth in her semi-final in 27.28secondsm ranking 11th overall to miss out by 0.27m although the same could not be said for British teammate Georgia Davies.
She stormed to the final as the fifth fastest in a British record of 26.84 while Halsall progressed to the 50m freestyle medal showdown as the joint-fourth quickest in 24.49.
Jemma Lowe was the other Brit to advance safely out of the semi-finals, this time in the 100m butterfly, and she was the best of the lot after clocking 57.16 for third overall.
Meanwhile Plymouth-based Olympic champion Ruta Meilutyte claimed her second gold medal and second championship record for Lithuania in the 100m breaststroke final.
Meilutyte proved her Olympic win in the 100m breaststroke at London 2012 was no fluke by taking the 50m breaststroke title in Turkey but she was not prepared to stop there also winning 100m medley silver.
And she added the world short course 100m breaststroke title to her growing collection after setting a new championship record of 1:03.52 with Alia Atkinson second and Moeller Rikke Pedersen third.
In the men's 50m backstroke Australian Robert Hurley won gold in 23.04 while Brazilian Nicholas Santos denied Olympic champion Chad le Clos at the touch in the 50m butterfly final.
Le Clos beat multiple Olympic and world champion Ryan Lochte to gold in the 100m butterfly however he was on the receiving end this time as Santos clocked a championship record of 22.22 to win by 0.04.
