10 is the max point total from ONE judge.

Actually it should be between -5 and 35. Because each entry can have a lowest possible score of -5 combining all 4 judges. (0 from AK, 0 from monda, 0 from me and -5 from Christmas) and 35 being a perfect score (10 from AK, 10 from monda, 10 from me and 5 from Christmas)
