Points System!!

I was thinking that since public voting can't be allowed in the show, y not have a points system, just like they use to have in SRGMP? Like on the elimination day, each mentor and the grand master would give each performance a score out of ten, and the eliminations would be done based on the performer who scored the least. Like they can keep the scores of the grand master a secret till the end but during the episode, show the scores given by each mentor. I think this system would work best since all the mentors and the grand master would have to justify their scoring and precisely tell where each contestant lost marks or why they got a perfect and stuff like that. What do u think?
