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 234.43818979485775 > 232.11543439159507.
IsChangePoint: Marked as a change because one of 5/9/2022 5:23:46 PM, 5/21/2022 3:14:39 PM, 5/22/2022 1:38:50 AM, 6/1/2022 6:40:18 PM, 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 -32.694596859641116 (T) = (0 -234.67903545709416) / Math.Sqrt((4.503353581737111 / (34)) + (0.23419509075561087 / (36))) is less than -1.9954689314290597 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (36) - 2, .025) and -0.05477757299744303 = (222.4914915380582 - 234.67903545709416) / 222.4914915380582 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.
