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 5.482321585434967 > 4.795326219776285.
IsChangePoint: Marked as a change because one of 10/11/2022 5:13:36 PM, 10/25/2022 5:34:05 PM, 11/3/2022 4:18:41 AM falls between 10/25/2022 1:30:53 PM and 11/3/2022 4:18:41 AM.
IsRegressionStdDev: Marked as regression because -13.5387838759383 (T) = (0 -6147.766167828389) / Math.Sqrt((74935.50250865189 / (10)) + (172219.39739119576 / (34))) is less than -2.0180817028167235 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (10) + (34) - 2, .025) and -0.3276602922605651 = (4630.5265011434385 - 6147.766167828389) / 4630.5265011434385 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.
