Print out some more information in bisect stats, including times for each step, std error difference in means, and a little explanation about how to interpret the confidence value.

Approximate size of regression: 2.45%,  0.14% std. err
Confidence in Bisection Results: 25%

Experimental - If confidence is less than 100%, there are most likely some other strong candidates for this regression. You can try increasing the repeat_count, or looking for a sub-metric that shows the regression more clearly.
