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 5.166614813632585 > 4.4656115303870125.
IsChangePoint: Marked as a change because one of 6/24/2022 10:21:49 PM, 6/30/2022 12:21:07 PM falls between 6/21/2022 9:29:01 PM and 6/30/2022 12:21:07 PM.
IsRegressionStdDev: Marked as regression because -13.946815571471316 (T) = (0 -4.923604920152937) / Math.Sqrt((0.05977794902580289 / (26)) + (0.024912740063290896 / (18))) is less than -2.0180817028167235 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (26) + (18) - 2, .025) and -0.20759991596659794 = (4.077182231510791 - 4.923604920152937) / 4.077182231510791 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.
