Take a look at the video and specifically at the start,

In my opinion, she ran into a headwind, then tailwind, thus the 0.0 reading.
10.49 could be legit.
I thought they already did several articles on this and it was wind-aided and the machine malfunctioned.
All other heats and jump at the time were over 4 on the gauge.
And the head then tail will not give a zero reading.
