I am happy to lose this bet. It seems that you have special insight into this OPC system.
I will assume that you are a 737-700 pilot for this question then:
given a report of Fair braking action first 2/3 of runway and poor braking action the last 1/3 of runway would YOU enter ''wet poor'' or ''wet fair'' into your OPC?
who knows, you might even fly for SW. I don't want you to get in any trouble for answering the question.
AND if you did enter wet-poor and saw you would have a 30' margin, would YOU have made the approach?
