### 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 31.32723645052601 > 26.122110055147612.
IsChangePoint: Marked as a change because one of 5/31/2022 5:02:26 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -2.8855534649833925 (T) = (0 -28.37978601728098) / Math.Sqrt((4.638634472115719 / (34)) + (8.000976170889645 / (6))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (6) - 2, .025) and -0.14060585607838436 = (24.881325890133493 - 28.37978601728098) / 24.881325890133493 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.
