The salary number that would convince joezydeco to "jump ship".

jump ship to the new opportunity (meaning a high number), or jump ship on the conversation (meaning his bare minimum number)?

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 :)
