Description of detection logic

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.
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 15.461021945380997 > 13.344494428066314.
IsChangePoint: Marked as a change because one of 5/2/2023 4:25:00 AM, 5/10/2023 10:36:48 PM falls between 5/2/2023 4:25:00 AM and 5/10/2023 10:36:48 PM.
IsRegressionStdDev: Marked as regression because -4.332787502342266 (T) = (0 -15.0332353346553) / Math.Sqrt((1.2583938000597372 / (8)) + (2.776673932075132 / (31))) is less than -2.026192463026769 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (8) + (31) - 2, .025) and -0.1671359924094019 = (12.880448750124758 - 15.0332353346553) / 12.880448750124758 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.
