sehinchee,
I agree with both Pete and Josephine in their assessment.
Additionally, I went out and bought John D. Roche "The Veteran's Survival Guide" (2nd Edition, Revised and Updated, 2007) because I read on one of the HADIT forums here about his book with great info to help Vets with their claims, along with HADIT . Very interesting read to say the least from a Vet who worked at the VA as a ratings official for many years.
Anyway, I've already read half the book yesterday; and one thing he mentioned under describing the "Rating Team" responsibility is Rule #2, which in part says, when requesting a copy of your files from the VA or sending them evidence, "submit it through your local congressional representative's office or your senator. Your request gets special handling considerations thus reducing the waiting time to obtain the records".
From his perspective, it appears to help if for nothing else to ensure the VA stay on their p's & q's and not lose your paperwork since the people who authorizes their funding (congress) has an interest.
