Medj, you have some mistakes when evaluating Petrosyan. At least in the first two points, because I saw the opposite.
1) Agree, it's enough to spoil it a couple of times, you don't have to do it constantly.
2) The criterion is clear: "He jokes funnily." If it said "he joked," I would agree. Currently, his humor is not relevant. There are funny shows on TV, but that's not Petrosyan.
Although... are you hinting that Petrosyan is completely adorable and deserves a 6/6? :)

В тихой однообразной жизни всегда так бывает: каждый отдельный день бесконечно долог, но месяцы и годы мчатся с непостижимой быстротой.
