Exceptions.Handling.ThrowAndCatchWhenFinally(kind: Software)

Description of detection logic

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 15.585828759148372 > 14.40504684505828.
IsChangePoint: Marked as a change because one of 11/30/2022 7:06:59 PM, 12/6/2022 5:44:36 AM falls between 11/27/2022 4:37:47 PM and 12/6/2022 5:44:36 AM.
IsRegressionStdDev: Marked as regression because -3.4644330068340223 (T) = (0 -14812.583819391015) / Math.Sqrt((6868774.955056067 / (27)) + (4142163.364375723 / (25))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (27) + (25) - 2, .025) and -0.17867525655752448 = (12567.145816442357 - 14812.583819391015) / 12567.145816442357 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.

Description of detection logic

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 15.585828759148372 > 14.40504684505828.
IsChangePoint: Marked as a change because one of 11/30/2022 7:06:59 PM, 12/6/2022 5:44:36 AM falls between 11/27/2022 4:37:47 PM and 12/6/2022 5:44:36 AM.
IsRegressionStdDev: Marked as regression because -3.4644330068340223 (T) = (0 -14812.583819391015) / Math.Sqrt((6868774.955056067 / (27)) + (4142163.364375723 / (25))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (27) + (25) - 2, .025) and -0.17867525655752448 = (12567.145816442357 - 14812.583819391015) / 12567.145816442357 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.
