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 28.276975984880213 > 26.579300224280544.
IsChangePoint: Marked as a change because one of 1/25/2022 6:54:35 PM, 3/11/2022 8:42:43 PM, 3/28/2022 7:37:41 AM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsRegressionStdDev: Marked as regression because -20.2144848920193 (T) = (0 -29.158570550595826) / Math.Sqrt((0.33603503818779634 / (39)) + (0.4695695862491762 / (13))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (39) + (13) - 2, .025) and -0.1718279597727317 = (24.882979030685476 - 29.158570550595826) / 24.882979030685476 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.
