### 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.
IsRegressionWindowed: Marked as regression because 1.00126233 > 849.6922812.
IsChangePoint: Marked as a change because one of 10/27/2022 12:34:03 AM, 11/3/2022 4:18:41 AM falls between 10/25/2022 1:30:53 PM and 11/3/2022 4:18:41 AM.
IsRegressionStdDev: Marked as regression because -10.095898208035912 (T) = (0 -970161108.4522417) / Math.Sqrt((2667573277142931.5 / (17)) + (2760326459160347 / (27))) is less than -2.0180817028167235 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (17) + (27) - 2, .025) and -0.2012358315666877 = (807635838.8235294 - 970161108.4522417) / 807635838.8235294 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
