The scale that can be used for giving scores to basically everything, from TV- shows to level of comedy. Most of the things on the luminert scale are ranked with a high, if not the highest score - 10/10. The way of selecting the fitting score is simple: you just have to determen if one part of your category has some kind of value, and you don't have to worry about the rest. If that is true, your "thing" is a perfect 10/10, and if not, then you would give it a 9/10. Scores lower than 9 are non-existent.
Darijan: "Kakegurui was an awful show, but it had great art so it must be a 10/10 on the luminert scale!"
