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. IsRegressionWindowed: Marked as regression because 14.65921994274809 > 11.766507442740314. IsChangePoint: Marked as a change because one of 10/2/2022 5:38:34 AM, 10/6/2022 12:41:43 AM falls between 9/27/2022 9:53:04 AM and 10/6/2022 12:41:43 AM. IsRegressionStdDev: Marked as regression because -17.35717414230426 (T) = (0 -16712.385048239965) / Math.Sqrt((803929.8360672664 / (35)) + (1355235.77981829 / (17))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (35) + (17) - 2, .025) and -0.4988347070165136 = (11150.252239292344 - 16712.385048239965) / 11150.252239292344 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. 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)
