Well, I think the only controversy was in how severely to penalize Zhang and Zhang for the interrruption in their program.
Interestingly, according to the judges protocols, they did receive a mandatory "fall" deduction, but they did not receive the mandatory decuction for "Interruption in Excess."
I didn't look up the exact definition and guidelines for that deduction. I guess it's like the deduction for Sasha's second "fall/not fall." It's up to the tech specialist or the referee to call it or not.
