### 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 1.5141732654600297 > 1.5047829101324972.
IsChangePoint: Marked as a change because one of 8/16/2022 10:54:40 PM, 8/27/2022 1:31:13 PM, 9/9/2022 3:12:19 AM, 9/23/2022 1:16:35 AM, 9/29/2022 7:42:19 AM, 10/19/2022 7:27:15 PM, 10/25/2022 2:56:59 AM falls between 10/16/2022 1:15:28 PM and 10/25/2022 2:56:59 AM.
IsRegressionStdDev: Marked as regression because -366.7528251007236 (T) = (0 -1514.3883990953564) / Math.Sqrt((0.6712288996611178 / (28)) + (0.43955708282761813 / (17))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (28) + (17) - 2, .025) and -0.05714952865543299 = (1432.5205262319666 - 1514.3883990953564) / 1432.5205262319666 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.
