PHYS 260 with Schossman curve??

Hello, does anyone know who has already taken Physics 260 with Mark Schlossman, and if the curve in the syllabus is accurate? In the syllabus, it says:

.
"Letter grades in this class are based upon a curve determined by the final scores As an example, a grading scheme similar to that from a previous class with on-campus exams is as follows. A 85%, B 70%, C 55%, D 40%, F Below 40%"

Since he simply said this is an "example" does anyone know if this is typically what he follows?
