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.
IsRegressionWindowed: Marked as regression because we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 10/10/2022 11:56:05 PM, 10/19/2022 4:51:05 PM falls between 10/10/2022 11:56:05 PM and 10/19/2022 4:51:05 PM.
IsRegressionStdDev: Marked as regression because -10.361043387474904 (T) = (0 -3812.7989575362167) / Math.Sqrt((36.17055310386064 / (2)) + (27487.56617292276 / (30))) is less than -2.0422724562973107 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (2) + (30) - 2, .025) and -0.09058834467448047 = (3496.093623368278 - 3812.7989575362167) / 3496.093623368278 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
