Although I am not an expert on this issue, I think that many who are successful in this, they have their own little tactic. There are statistics on the basis of which you can determine a mean value for each individual auction item. This allows you to, statistically, predict that price will be the final one.
Of course, you can always take your current hunch here. Several times, as I've been able to predict the approximate, but not exact, final price, led me to exactly that hunch.
What I want to say, there is no scientific approach.
