Description of detection logic

IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because 14.158405311935399 < 17.70875980330163.
IsChangePoint: Marked as a change because one of 9/27/2023 11:11:59 PM, 10/5/2023 4:37:42 AM, 10/11/2023 8:44:35 PM falls between 10/3/2023 8:20:31 AM and 10/11/2023 8:44:35 PM.
IsImprovementStdDev: Marked as improvement because 5.495980289151989 (T) = (0 -14.077941563722096) / Math.Sqrt((4.632298714687833 / (197)) + (3.0506941750961567 / (26))) is greater than 1.9707562704893595 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (197) + (26) - 2, .975) and 0.12779165897739458 = (16.140572041786093 - 14.077941563722096) / 16.140572041786093 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
