IsRegressionStdDev: Marked as regression because -16.585809256751453 (T) = (0 -8309.328055276403) / Math.Sqrt((181196.42792702996 / (31)) + (15894.789814791753 / (6))) is less than -2.0301079282477414 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (31) + (6) - 2, .025) and -0.22543523464214033 = (6780.715798255097 - 8309.328055276403) / 6780.715798255097 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
