Playing The Devilâ€™s Advocate – Nathan Hartono in Sing! Chinaâ€™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.
