### Description of detection logic
```
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because 1.0331159499300493 < 2.197056011501806.
IsChangePoint: Marked as a change because one of 3/3/2023 11:43:56 AM, 5/3/2023 7:05:50 AM, 5/9/2023 7:24:34 AM falls between 4/30/2023 6:17:41 PM and 5/9/2023 7:24:34 AM.
IsImprovementStdDev: Marked as improvement because 23.61318979081387 (T) = (0 -1.0866687421861267) / Math.Sqrt((0.04271380623636815 / (299)) + (0.062496307806191094 / (26))) is greater than 1.967335607330539 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (26) - 2, .975) and 0.5230293548425967 = (2.2782717410785716 - 1.0866687421861267) / 2.2782717410785716 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
