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 29.0212977582846 > 28.191649916447016.
IsChangePoint: Marked as a change because one of 7/13/2022 11:09:36 AM, 7/14/2022 8:56:55 AM falls between 7/5/2022 7:51:46 PM and 7/14/2022 8:56:55 AM.
IsRegressionStdDev: Marked as regression because -5.441739498239833 (T) = (0 -29081.65679824561) / Math.Sqrt((7954592.762253564 / (43)) + (7286.427410029882 / (2))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (43) + (2) - 2, .025) and -0.0884586327275392 = (26718.20124699702 - 29081.65679824561) / 26718.20124699702 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.
