I saw this as well. Neisi Dajomes (of Ecuador) effectively clinched the gold with her 2nd clean and jerk. I actually think her outburst on her last lift started out as a celebration (she also screamed her head off when she succeeded on her 3rd snatch lift earlier) and then morphed into disappointment at the judges' "no lift" call (which was later overturned by the jury).
If you thought that was dramatic, did you see the reaction of the Korean lifter when she was "no-lifted" by the judges? That was intense.
Dajomes is a great story. She is the first Ecuadorian woman to win a gold medal EVER. And congrats to Kate Nye, who won a rare Olympic medal for the US in weightlifting.
If you watch the replay on nbcolympics.com, the analyst there does a good job of explaining these calls by the jury. It's not about holding the lift at the top a specific time, but the key components are catching the lift with a locked elbow (no "press-out" allowed, not even slightly), and demonstrating balance and control.
FWIW, it's a 5-person jury, and apparently they changed the rules so that only a majority of the jury is needed to overturn the judges' decision (previously the jury had to be unanimous to overturn).
Watch the highly anticipated women's 76kg Group A competition at Tokyo International Forum.
