I prefer use the panniculus grading: Grade 1 - Panniculus barely covers the hairline of the mons pubis but not the genitalia. Grade 2 - Extends to cover the genitalia. Grade 3 - Extends to cover the upper thigh. Grade 4 - Extends to cover the mid thigh. Grade 5 - Extends to cover the knees or beyond. Grade 6 - Extends to cover planet Earth. Grade 7 - Extends to cover holes in the ozone layer. Grade 8 - Extends to cover the solar system. Grade 9 - Extends to cover the Milky Way. Grade 10 - Extends into heaven.
