That's the difference between the best and mediocre. The best maintain their shooting over the whole competition, mediocre ones crack with pressure, she will get the experience for next time. She was 65 winner had 70 shots. That 5/70 difference which is a lotShe did very well in the first 2 rounds : 23 + 22, then got an average 20 in the 3rd.
If she was capable of maintaining her level she would have made it to the final..
