AM2 4MAN

After electing to go the DRO way, earlier this year,today I got the piece of mail from the VA. After reading through the statementof case, it said that 2 of my ratings were being increased to 10% each and theother will stay at 0% effective Jan,2009 The packet of papers came with a VA form 9 at the back. Now on the front it says under the What You Will Need To do- To complete your appeal,you must file a formal appeal. Does that mean that I need to fill out form 9with everything I stated in my NOD? I am happy with one of the three decisionsthat is stated in my statement of case that I received today, but I havemedical evidence that my symptoms are worse and getting worse on the other two. My next question is regarding the pay; it says in the statement of case thatthe increases will be effective Jan 2009. I had one decision rating at 10% frombefore that I did not appeal. So now I will have 3 ratings at 10%. How does theVA determine the total disability pay for this? Will my rating still be 10% orwill increase? And if so will I get back pay to Jan 09?
