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 12.567095064211433 > 11.452644017910078.
IsChangePoint: Marked as a change because one of 3/31/2022 1:45:25 PM, 5/29/2022 1:52:27 AM, 5/30/2022 3:57:24 AM, 5/31/2022 8:51:40 AM falls between 5/22/2022 6:37:49 PM and 5/31/2022 8:51:40 AM.
IsRegressionStdDev: Marked as regression because -4.629393463390666 (T) = (0 -12.313829476686287) / Math.Sqrt((1.8132960961181057 / (60)) + (0.13326831971383152 / (6))) is less than -1.997729654317006 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (60) + (6) - 2, .025) and -0.0941950330130159 = (11.253779358491942 - 12.313829476686287) / 11.253779358491942 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.
