The problem I have with this approach is that with many companies, particularly larger established ones like AmaGoogSoft, base salary is just one portion of a compensation package that might have contributions of up to 50% from stock, bonus, incentive pay, benefits/matching, and perks. If you start anchoring on one piece of that puzzle, it limits your ability to move on others. If the goal of negotiation is to maximize your total offer (which it should be), then the only reasonable answer to the question is "depends on total compensation factors".
