### 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 250.7730078125 > 233.2419718309859.
IsChangePoint: Marked as a change because one of 11/30/2022 7:06:59 PM, 12/2/2022 2:36:06 PM, 12/12/2022 10:47:19 AM, 12/13/2022 2:17:54 AM falls between 12/4/2022 6:53:17 AM and 12/13/2022 2:17:54 AM.
IsRegressionStdDev: Marked as regression because -14.929327887204074 (T) = (0 -251207.96190571584) / Math.Sqrt((108955328.7919482 / (56)) + (439421.94975208765 / (3))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (56) + (3) - 2, .025) and -0.09404453917339915 = (229614.01744714615 - 251207.96190571584) / 229614.01744714615 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.
