Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 1.2216164397496088 > 1.203409490876203.
IsChangePoint: Marked as a change because one of 2/1/2022 1:24:52 PM, 3/17/2022 6:54:53 PM, 3/31/2022 9:26:55 AM, 4/5/2022 2:02:34 AM falls between 3/26/2022 9:07:40 PM and 4/5/2022 2:02:34 AM.
IsRegressionStdDev: Marked as regression because -9.893272699275979 (T) = (0 -1212.3896114400968) / Math.Sqrt((219.6453056443448 / (34)) + (688.8270541293093 / (22))) is less than -2.0048792881871513 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (22) - 2, .025) and -0.05279820303833189 = (1151.5878427045095 - 1212.3896114400968) / 1151.5878427045095 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.
