ELI5: How has FloJo's 100m world record remained unbroken for so long compared to men's 100m sprint?

The wind gauge was incorrect during her world record time, which should have disqualified that specific run. She was still the fastest of the bunch on each other heat. The IAAF decided not to penalize her for the illegal tailwind, so her record stood.

It's also speculated that she was using HGH, and her retiring the year before mandatory drug testing was instituted. One person came forward and claimed to sell her some, but it was dismissed at the time. The Olympic committee at the time claimed they singled her out and did rigorous drug testing, and failed to find anything, though the doctor who did the examination was accused of covering up failed drug tests on other occasions.
