Bolt 9.61?

1 Fraser, Shelly-Ann 22 Mvp Track Club 11.19 10.88 -1.5
2 Stewart, Kerron 25 Unattached 11.34 10.93 -1.5

If the wind reading is correct these are insanely fast times, possibly worth a sub 10.7 with a 2.0 m/s tailwind.
Fraser’s SB was 11.15 (+ 1.2) and a windy 11.10 (+3.2). How do you effectively drop 0.4s within three weeks?
