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 1.3008547546093907 > 0.5464235960954122.
IsChangePoint: Marked as a change because one of 5/30/2022 4:33:23 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -20.49311078470349 (T) = (0 -1.3595083536345105) / Math.Sqrt((0.024075186439821712 / (30)) + (0.013879068102020496 / (10))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (30) + (10) - 2, .025) and -2.3954358276727152 = (0.4003928869909872 - 1.3595083536345105) / 0.4003928869909872 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 as regression because Edge Detector said so.
