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 5.213223912617216 > 3.9288893329490264.
IsChangePoint: Marked as a change because one of 10/11/2022 2:16:14 AM, 10/18/2022 1:35:00 AM falls between 10/7/2022 9:25:17 PM and 10/18/2022 1:35:00 AM.
IsRegressionStdDev: Marked as regression because -72.82716658634978 (T) = (0 -5.193400276503748) / Math.Sqrt((0.0002998150850715373 / (21)) + (0.0115999224016347 / (30))) is less than -2.0095752371279447 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (21) + (30) - 2, .025) and -0.39041474332314413 = (3.735144712354908 - 5.193400276503748) / 3.735144712354908 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.
