### 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 890.9868287037037 > 818.7193515624999.
IsChangePoint: Marked as a change because one of 4/20/2022 2:49:46 PM, 4/28/2022 4:25:37 PM, 5/11/2022 3:41:15 PM, 5/28/2022 3:04:49 PM, 6/2/2022 2:22:06 PM, 6/7/2022 9:00:42 AM falls between 5/29/2022 5:15:01 PM and 6/7/2022 9:00:42 AM.
IsRegressionStdDev: Marked as regression because -12.589728107864358 (T) = (0 -941559.8861007346) / Math.Sqrt((3086336224.1759415 / (41)) + (279880439.2422121 / (31))) is less than -1.9944371117706434 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (41) + (31) - 2, .025) and -0.1399528279202919 = (825963.9022243564 - 941559.8861007346) / 825963.9022243564 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.
