### 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 1.9050833796296296 > 1.8348061538461538.
IsChangePoint: Marked as a change because one of 2/26/2022 10:27:55 AM, 3/3/2022 7:35:51 PM, 3/25/2022 7:34:40 AM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsRegressionStdDev: Marked as regression because -323.11043860323406 (T) = (0 -1906789.982326007) / Math.Sqrt((1353416.1955267477 / (28)) + (4889418.773011583 / (25))) is less than -2.007583770314729 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (28) + (25) - 2, .025) and -0.0913318994129754 = (1747213.6417451596 - 1906789.982326007) / 1747213.6417451596 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.
