### Description of detection logic
```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.
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 198.07930025600388 > 167.48253939087434.
IsChangePoint: Marked as a change because one of 5/20/2022 10:46:48 AM, 5/24/2022 7:58:36 AM falls between 5/15/2022 3:27:46 PM and 5/24/2022 7:58:36 AM.
IsRegressionStdDev: Marked as regression because -91.306682889007 (T) = (0 -196045.6815454997) / Math.Sqrt((996200.490846422 / (51)) + (2506293.6081947945 / (18))) is less than -1.9960083540247138 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (51) + (18) - 2, .025) and -0.22786826739665736 = (159663.44823061384 - 196045.6815454997) / 159663.44823061384 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.
