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 3.3361165833333333 > 3.2124107604166663. IsChangePoint: Marked as a change because one of 2/26/2022 10:27:55 AM, 3/3/2022 7:35:51 PM, 3/10/2022 2:45:04 PM, 3/15/2022 12:53:39 AM falls between 3/6/2022 12:59:26 AM and 3/15/2022 12:53:39 AM. IsRegressionStdDev: Marked as regression because -10.576200230213354 (T) = (0 -3291588.49320055) / Math.Sqrt((7041169277.0097475 / (42)) + (1203226296.4707193 / (20))) is less than -2.0002978220134566 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (42) + (20) - 2, .025) and -0.05096808734214087 = (3131958.555968007 - 3291588.49320055) / 3131958.555968007 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. ``` ### Docs [Profiling workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/profiling-workflow-dotnet-runtime.md) [Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)
