Playing The Devil’s Advocate – Nathan Hartono in Sing! China’s final
Given the swirling controversy about how Sing! China magically brought out 11 more judges to cause Nathan Hartono to lose by 45 votes to 47, I would like to present an alternative viewpoint after thinking about it.
Watching on http://v.youku.com/v_show/id_XMTc1MTQyNjYyNA (from 136:00), it could be seen that the results went as follows:
While watching the video, it showed that the emcee needed to instruct the judges on the way the system worked – to slot the star into the box and not to take it in and out repeatedly, which shows that perhaps a bit of coaching should have been done prior to the judging process.
A hypothesis may remain a hypothesis. However, a bit of Mathematics may help in this case.
