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 26.085400827058184 > 23.60279411972659.
IsChangePoint: Marked as a change because one of 1/10/2022 3:45:28 PM, 1/11/2022 6:33:01 AM falls between 1/2/2022 6:26:27 PM and 1/11/2022 6:33:01 AM.
IsRegressionStdDev: Marked as regression because -8.34583029912319 (T) = (0 -25.704588368215983) / Math.Sqrt((1.7245020495994894 / (55)) + (0.39918140519116574 / (3))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (55) + (3) - 2, .025) and -0.1516129194229966 = (22.320510594041437 - 25.704588368215983) / 22.320510594041437 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.
