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 9.27990074097555 > 7.826822110305982.
IsChangePoint: Marked as a change because one of 9/7/2022 7:08:29 PM, 9/15/2022 1:10:12 AM falls between 9/6/2022 1:06:44 PM and 9/15/2022 1:10:12 AM.
IsRegressionStdDev: Marked as regression because -8.781475164700971 (T) = (0 -10.514186900847792) / Math.Sqrt((1.1535214656356942 / (17)) + (1.9143541746928057 / (35))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (17) + (35) - 2, .025) and -0.41318900794299906 = (7.440042939586664 - 10.514186900847792) / 7.440042939586664 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.
