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 5.976931384952766 > 4.890526134441379.
IsChangePoint: Marked as a change because one of 9/29/2022 6:03:53 PM, 10/6/2022 12:41:43 AM falls between 9/27/2022 9:53:04 AM and 10/6/2022 12:41:43 AM.
IsRegressionStdDev: Marked as regression because -9.42584619881022 (T) = (0 -5632.430761933109) / Math.Sqrt((102688.16068267588 / (23)) + (157823.7163655221 / (29))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (23) + (29) - 2, .025) and -0.19985893096661556 = (4694.244145347637 - 5632.430761933109) / 4694.244145347637 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.
