### 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 21.57512939149845 > 21.42536922196871.
IsChangePoint: Marked as a change because one of 2/15/2023 6:58:43 PM, 3/14/2023 5:06:59 PM, 4/12/2023 4:44:56 PM, 4/25/2023 3:46:39 AM falls between 4/12/2023 4:44:56 PM and 4/25/2023 3:46:39 AM.
IsRegressionStdDev: Marked as regression because -32.18850953975301 (T) = (0 -23227.49911708104) / Math.Sqrt((41241.6486963708 / (13)) + (137663.86400544303 / (36))) is less than -2.011740513728388 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (13) + (36) - 2, .025) and -0.1311119496227229 = (20535.101874600885 - 23227.49911708104) / 20535.101874600885 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.
