Thank you for sharing this information. It's ok if you don't know all the terminology or jargon.
Was yours a legacy claim, Higher Level Review, or formal appeal to the Board of Veterans Affairs?
I don't want you to worry, but some of us (including myself) have been told they are siding in our favor, but when the decision letter arrives we find that we were denied to some extent. We all have our fingers crossed that they really will find in your favor. If you have a VSO who has access to the VA system (VBMS), they can look up decision letters and tell you what was decided before it arrives in the mail. In the end, it is a case where you really don't know for certain until the decision letter arrives. Additionally, even if they find in your favor, double-check everything. The VA is supposed to maximize benefits, but often misses things or low balls ratings. Trust, but verify.
