Jump to the new job. Doesn't necessarily have to be a high number, but if I'm not looking for a lateral (meaning, I like my current job), then it should be significantly larger than what I'm making in salary/benefits today.

I can see how that's ambiguous, and this is just an assumption, but I assumed he meant "jump ship to a new opportunity" because starting off with the lowest number you'd accept seems like a bad negotiation strategy :)
