scores are added up, and the lowest and highest are thrown out (sometimes 2 high and 2 low depending on how many judges are on the panel)
Example:
Kai : judges 1,2,3,4,5, give 1's...judges 6, scores him a 3, judge 7 gives a 1.....3/1 are thrown out....leaving 5 for the total
Vic: judges 1,2,3, give a 2, judges 4,5,6 give a 3, judge 7 gives a 1 ..........1/3 are thrown out...leaving 12 for the total
