### 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 423.37709821428575 > 13.955767172445656.
IsChangePoint: Marked as a change because one of 7/15/2022 5:00:56 PM, 7/18/2022 2:17:16 AM falls between 7/8/2022 10:31:34 AM and 7/18/2022 2:17:16 AM.
IsRegressionStdDev: Marked as regression because -215.66452603817729 (T) = (0 -427496.7062783447) / Math.Sqrt((757370.4008776997 / (72)) + (51529833.63553704 / (14))) is less than -1.9886096669751727 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (72) + (14) - 2, .025) and -31.5089580427055 = (13150.120213535058 - 427496.7062783447) / 13150.120213535058 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.
