I just received my rating decision. However, I cannot combine the individual ratings to arrive at the combined rating they provide -- and yes, I am using the combined ratings table. My ratings are as follows: sleep apnea (50%), healed fracture, right hip (30%), acne/folliculitis on face, neck, chest, back & legs (10%), vitreous syneresis, left eye (10%), tinnitus (10%), hypertension (10%), anxiety disorder (10). The combined ratings table combines these ratings to 84%, which should be rounded down to 80%. However, the rating decision letter rates me at 90% disabled! The only thing I can figure is that they added a bi-lateral factor for my acne on my legs combined with my hip fracture. Is this possible? If so, this seems to be an absurb reason for granting an extra 10%. Is there anything else I'm missing?
