### 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 1.7580663404576014 > 1.7188841895484979.
IsChangePoint: Marked as a change because one of 9/26/2022 8:26:31 AM, 9/27/2022 11:22:50 AM, 10/11/2022 8:42:28 PM, 10/17/2022 12:47:34 PM, 10/26/2022 7:11:30 AM, 11/1/2022 2:33:16 AM falls between 10/23/2022 1:14:54 PM and 11/1/2022 2:33:16 AM.
IsRegressionStdDev: Marked as regression because -42.395008575906566 (T) = (0 -1819.5453508307173) / Math.Sqrt((222.8134718506323 / (24)) + (268.67754679064495 / (26))) is less than -2.010634757623041 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (24) + (26) - 2, .025) and -0.11507452436828657 = (1631.7701741608064 - 1819.5453508307173) / 1631.7701741608064 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.
