### Payloads [Baseline]() [Compare]() ### Histogram ### Edge Detector Info [Collection Data]() #### System.Tests.Perf_UInt64.TryFormat(value: 0) ```log ``` ### 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. IsRegressionWindowed: Marked as regression because 267.77236034758965 > 248.3236066649993. IsChangePoint: Marked as a change because one of 7/28/2022 3:42:13 AM, 10/11/2022 2:16:14 AM, 10/18/2022 9:26:37 AM falls between 10/7/2022 9:25:17 PM and 10/18/2022 9:26:37 AM.

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.
