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 40.53748460547599 > 38.60607866558386.
IsChangePoint: Marked as a change because one of 3/21/2022 1:28:14 PM, 4/25/2022 11:05:49 AM, 5/10/2022 5:59:50 PM, 5/17/2022 3:30:02 AM falls between 5/8/2022 12:35:08 PM and 5/17/2022 3:30:02 AM.
IsRegressionStdDev: Marked as regression because -21.517636004594916 (T) = (0 -41.320676498311634) / Math.Sqrt((0.34221470547372784 / (30)) + (1.0462944700215853 / (37))) is less than -1.997137908391408 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (30) + (37) - 2, .025) and -0.11574653043808139 = (37.03410709427676 - 41.320676498311634) / 37.03410709427676 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.
