My win rate for 4 goods is 95%, 5 goods 83%, and 6 goods is 51%. I need to work on my 6 good negotiating...anyways my point here is that your negotiating strategy was probably different from what you should be doing. Always at the beginning try to use each good so you know which one to use. For example, the 5 good negotiation: You should use each options once, then work on it from there. 6 Good: 5/6 of the options, then use the 6th on the second turn. Etc.
