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 61.60986 > 54.60170625.
IsChangePoint: Marked as a change because one of 11/17/2021 1:22:14 PM, 2/15/2022 12:48:49 AM, 2/17/2022 2:02:19 AM falls between 2/8/2022 9:17:51 AM and 2/17/2022 2:02:19 AM.
IsRegressionStdDev: Marked as regression because -43.05192153695367 (T) = (0 -61619082.28327228) / Math.Sqrt((107357720034.6918 / (30)) + (319397353119.8285 / (7))) is less than -2.0301079282477414 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (30) + (7) - 2, .025) and -0.18341101400445306 = (52069045.79564815 - 61619082.28327228) / 52069045.79564815 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.
