Okay, now we have some drama.
People are questioning why Luo Rui only received a score of 8.433 in execution for her routine, and then the logical explanation was that she hit the low bar with her feet once, which should cause a 0.5 deduction on the execution score. However, according to the code of points, this deduction only applies if the rhythm of the routine is affected -- i.e., if there is a pause or if the movement she performs does not follow smoothly. People are now discussing on Twitter that the rhythm of the routine was never broken, so she should have never been deducted.
My opinion: she should have won. Rebeca should have been the bronze medalist, and I would not even be mad if Kovacs had been scored higher and earned the bronze medal. The uneven bars final was great but the way gymnasts were scored leaves the doors open for discussion.
