BATNA is best alternative to a negotiated agreement, meaning, it's what happens if you don't agree. So really, a BATNA in a salary negotiation for a new position is not taking the position. In an existing position where you're going for a raise, your BATNA is quitting.
BATNA isn't a bargaining position, it's your fallback option in case bargaining fails. I think you're talking more about your "bottom line", which is the lowest number you're willing to accept. A good negotiator goes in knowing his/her BATNA and bottom-line, but they're separate concepts.
I also completely disagree with you disregarding objective criteria. I used my recent purchase of a 2-year old vehicle as a way to gain some extra experience in negotiating and work on different approaches with two separate dealers. My initial approach with the dealer I ultimately bought from, was to derive my bottom-line number from objective criteria, but to show no strong evidence to how I got the numbers I was offering. I got nowhere with that approach. The sales manager didn't even come out to stop me from leaving when negotiations with the salesman got nowhere. We were only $1,000 from my bottom-line (which he didn't know) and about $1,800 away from our stated positions.
I came back a few days later with reasonable evidence based on market data of the particular model I was buying, as well as reasons why I'd go spend more money on another manufacturers' similar, but nicer model in the same class. They ended up coming down the full $1,800 after I was about to walk away again.
This works time and time again. Unless you're in a position where you completely don't care if you complete a purchase/sale/agreement, then holding onto unrealistic positions will never get you very far. My father-in-law likes to buy and sell stuff, but he pretty much only deals in unrealistic offers, and he rarely ends up buying or selling anything, even though he spends a decent amount of time looking.
