If Boyle was to make a podium it would be one of the more remarkable achievements in New Zealand sport, even in a post-Olympic year.
If she breaks the cycle of underachievement, it could be the catalyst towards further success.
Courtesy of Boyle's Olympic performance, a tentative reprieve was possible. She came fourth in the 800m freestyle with a personal best, 2.4s from bronze.
Boyle further helped restore the sport's reputation at December's short-course (25m pool) world championships in Turkey by claiming gold in the 800m (New Zealand's first since Moss Burmester in the 200m butterfly in 2008) and bronze in the 400m.
After years of controversy within SNZ's administrative and competitive ranks, one swimmer had started to break the shackles of mediocrity.
