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 3.2503316809794383 > 0.5969972470119715.
IsChangePoint: Marked as a change because one of 12/28/2022 5:13:50 PM, 2/2/2023 5:46:53 AM, 2/7/2023 8:22:47 AM falls between 1/29/2023 5:12:48 PM and 2/7/2023 8:22:47 AM.
IsRegressionStdDev: Marked as regression because -13549.869174148425 (T) = (0 -3.25045817486954) / Math.Sqrt((1.7211857484899721E-07 / (33)) + (8.833356403838247E-07 / (26))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (33) + (26) - 2, .025) and -4.722057270858919 = (0.5680576095285437 - 3.25045817486954) / 0.5680576095285437 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.
