IsRegressionStdDev: Marked as regression because -32.872629190566606 (T) = (0 -63.17060853119569) / Math.Sqrt((0.16305463689349234 / (12)) + (0.23176640613545796 / (37))) is less than -2.011740513728388 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (12) + (37) - 2, .025) and -0.07912064147861463 = (58.53896784389104 - 63.17060853119569) / 58.53896784389104 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 as regression because Edge Detector said so.
