6. Heena Sidhu, 25m Pistol and 10m Air Pistol

Heena Sidhu joined an exclusive club when she won two medals for India in Shooting. Her first came in the 10m Air Pistol when she finished behind fellow Indian Manu Bhaker. She went one better in 25m Pistol, claiming the Gold medal and creating a Games Record in the process.
Sidhu did participate in both these events in Rio but could not finish in a medal spot. However, she did not let her defeat in Rio get to her head as she went on to win a Gold and a Silver in this year's CWG.
It is clear that Sidhu would've ended up with a Bronze medal if we compare her 10m Air Pistol scores to those of the Rio medallists.
In 25m Pistol, however, Sidhu's score of 18 after a certain number of rounds means that she would've made it through to the final two in Rio, potentially ending up with a Silver or a Gold medal.
