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 146.8940003337784 > 129.8322732802931.
IsChangePoint: Marked as a change because one of 4/2/2022 8:37:19 AM, 5/11/2022 9:09:01 PM, 5/30/2022 10:25:35 AM, 6/7/2022 9:00:42 AM falls between 5/29/2022 5:15:01 PM and 6/7/2022 9:00:42 AM.
IsRegressionStdDev: Marked as regression because -10.35683090484025 (T) = (0 -143991.98980050805) / Math.Sqrt((30692662.111061636 / (20)) + (105918239.54238056 / (52))) is less than -1.9944371117706434 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (52) - 2, .025) and -0.15731361014371076 = (124419.16222053906 - 143991.98980050805) / 124419.16222053906 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.
