That's the election once a week, and in the first week who will be the champion.
Up to 4 weeks.
And after getting 4 winners in one month, the 4 people will be randomized again, who is their best 4 picture.
And they will be the champions 1, 2, 3, and 4.
Maybe like that, and if you want to know more, you can ask @sultan-aceh.
