IsRegressionStdDev: Marked as regression because -31.92670258870068 (T) = (0 -4526946.605940852) / Math.Sqrt((1537813277.4947698 / (40)) + (1808997884.7097666 / (18))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (40) + (18) - 2, .025) and -0.09067005533135562 = (4150610.520397504 - 4526946.605940852) / 4150610.520397504 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.
