Thank you for your replies. I had thought that an average in points per hand over a significant number of hands might be indicative of something more than luck. I guess its true the Bridge 4 is tough to determine much from, given the small number of hands.
I regularly play "just play bridge' or 'Bridge 4' so I know what is a good average score FOR ME. But I am not sure whats a good score more broadly and hoped someone could share their thoughts.
