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 2.7729823703703707 > 2.636088477857143.
IsChangePoint: Marked as a change because one of 2/26/2022 10:27:55 AM, 3/4/2022 7:13:54 PM, 3/6/2022 9:32:10 PM, 4/11/2022 9:20:21 PM, 4/12/2022 5:02:33 PM falls between 4/4/2022 4:14:58 AM and 4/12/2022 5:02:33 PM.
IsRegressionStdDev: Marked as regression because -17.741245187531494 (T) = (0 -2765662.3833242636) / Math.Sqrt((4682424442.616723 / (54)) + (125196571.86128692 / (3))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (54) + (3) - 2, .025) and -0.07840102155025906 = (2564595.4779869146 - 2765662.3833242636) / 2564595.4779869146 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.
