These were collected by Jeff last week: https://docs.google.com/a/google.com/document/d/1erjepFVXplUFXCybBd8aojjEDgoDGfM4V-j_GewPWOg/edit

In the examples that he collected, I think that most of the confidence score numbers were from the old confidence function. Some of the actual results still don't fully line up with intuition, for example:

    [67, 68], [65, 65, 67] -> 80%
    [3, 3, 3], [2, 2, 2, 3] -> 90%

In general, the t-test is always giving either 0 or at least 80 (sort of like how it is for alerts the dashboard).
