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 110.80196746428571 > 94.883617040625.
IsChangePoint: Marked as a change because one of 12/4/2021 9:11:00 PM, 2/14/2022 9:07:48 PM, 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 -6.050361917144816 (T) = (0 -111943777.68537414) / Math.Sqrt((43200723891787.49 / (28)) + (46052215898627.13 / (7))) is less than -2.034515297446192 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (28) + (7) - 2, .025) and -0.1820757327137056 = (94701020.06779502 - 111943777.68537414) / 94701020.06779502 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.
