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 12.33486758440217 > 10.988762412467347.
IsChangePoint: Marked as a change because one of 1/6/2023 6:58:01 PM, 1/10/2023 1:28:02 AM falls between 1/1/2023 3:57:25 AM and 1/10/2023 1:28:02 AM.
IsRegressionStdDev: Marked as regression because -65.15302982635818 (T) = (0 -12.330547581320218) / Math.Sqrt((0.023020926501355954 / (34)) + (0.00030894222978022576 / (13))) is less than -2.0141033888794695 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (13) - 2, .025) and -0.16263257818109503 = (10.605713114121576 - 12.330547581320218) / 10.605713114121576 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.
