A Washington Post article noted this troubling internal VA finding:

According to an internal memo on the mystery-caller program that is buried deep in the VA Web site, 22 percent of the answers the callers got were "completely incorrect," 23 percent were "minimally correct" and 20 percent were "partially correct." Nineteen percent of the answers were "completely correct," and 16 percent "mostly correct."

I guess the moral is to be careful in following any advice you get; you may want to double check by asking the question two different times to two different VA representative... or seek a second opinion elsewhere too if it's an important question.
