### 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 167.78014085837506 > 155.48599795544052.
IsChangePoint: Marked as a change because one of 12/12/2022 5:25:39 PM, 12/14/2022 5:20:21 PM, 1/5/2023 11:35:29 PM, 1/18/2023 8:37:25 PM, 1/30/2023 9:42:46 PM, 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 -226.9268252525918 (T) = (0 -167.10178079612837) / Math.Sqrt((0.04249295579879628 / (19)) + (0.19009734036756123 / (40))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (19) + (40) - 2, .025) and -0.12806932263377016 = (148.13077303262352 - 167.10178079612837) / 148.13077303262352 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.
