It's just confusing because the 70% and 50% both show up as service connected disabilities with separate ratings, symptoms and different impairments that affect my social life, relationships, occupation and daily routine.. I also looked at my online health records in reference to my compensation exam for an increased rating, the question-air filled out by the c&p examiner states that there is a definite difference between symptoms of the two ratings which warrant a new and separate service connected rating. Do they normally leave the previous rating there on the list of disabilities? I'm very aware that ebenefits is slow as mud but I also know that the VA had about a 30% error rate with compensation claims.
