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.
IsRegressionWindowed: Marked as regression because 20.741131736417078 > 20.037930119042237.
IsChangePoint: Marked as a change because one of 9/28/2022 6:40:13 PM, 10/14/2022 9:06:25 AM, 10/18/2022 1:35:00 AM falls between 10/7/2022 6:01:23 PM and 10/18/2022 1:35:00 AM.
IsRegressionStdDev: Marked as regression because -4.930455081974264 (T) = (0 -21.4252034370791) / Math.Sqrt((0.4397282191251158 / (36)) + (2.036901167442989 / (11))) is less than -2.0141033888794695 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (36) + (11) - 2, .025) and -0.11388374744475258 = (19.234685384564127 - 21.4252034370791) / 19.234685384564127 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
