Exactly. The lower bound I'm prepared to give is always a raise from my current salary. I may be prepared to accept less if the opportunity is right, but my only purpose in offering this information in the first place is to get to the next stage of the process. It is a tricky thing to keep as much negotiating leverage as possible while still signaling that you can come to an agreement, which is why I only offer the number if I feel like I won't progress to the next stage without it.
