It's not some strategy to not fall. Both of her Olympic runs look like this. According to the AP, this is a typical performance for Swaney. She has finished near the bottom in the dozen or so international events she competed in over the last four years.
As the AP notes, she's had a number of strange goals in her life, including trying out for the Oakland Raiders and running for governor of California at age 19. Her Olympic dream began as a hope to do skeleton for Venezuela. When that didn't work out, she changed the target. She only started skiing eight years ago. "I still want to inspire people to get involved with athletics or a new sport or a new challenge at any age in life," she said.
Swaney didn't do anything illegal to land a spot on the Hungarian Olympic team. She joined the team because her grandfather was Hungarian. She collected the required number of FIS points to compete in the Olympics, likely at a great personal expense.
