Sure, I've seen similar ranges; that's why they toss out the high and the low scores ... have seen similar ranges on skating skills, and on multi-judge panels, including a wide range of comments (with a Fantatic spin; great entry; +3 from J1, and Weak fly, need more rotations; -1 from J2). If you check out the protocols on comps, you'll see it ... judges are human, and things happen.
We don't get protocols on OBO anymore, but, back in the day ... yup. It happened.
