### 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 1.2516630014565961 > 1.2444290418657364.
IsChangePoint: Marked as a change because one of 11/21/2022 6:40:27 PM, 1/3/2023 6:29:42 AM, 1/17/2023 5:52:57 PM, 1/20/2023 8:02:54 AM, 2/2/2023 5:46:53 AM, 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 -107.70423255441933 (T) = (0 -1249.7674070202208) / Math.Sqrt((1.170859898871218 / (32)) + (8.31256259579378 / (26))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (32) + (26) - 2, .025) and -0.05423122105795802 = (1185.4775139044311 - 1249.7674070202208) / 1185.4775139044311 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.
