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 372.1873841035285 > 205.21028841003792.
IsChangePoint: Marked as a change because one of 6/15/2022 1:30:25 PM, 7/6/2022 5:19:04 PM, 7/11/2022 5:54:09 PM falls between 7/3/2022 4:26:07 AM and 7/11/2022 5:54:09 PM.
IsRegressionStdDev: Marked as regression because -29.545336687002926 (T) = (0 -366.94676882425546) / Math.Sqrt((88.2944163055655 / (25)) + (655.7260155053721 / (21))) is less than -2.0153675744421933 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (25) + (21) - 2, .025) and -0.9036213804448788 = (192.76247503508262 - 366.94676882425546) / 192.76247503508262 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.
