### Payloads [Baseline]() [Compare]() ### Histogram #### Benchstone.BenchF.NewtR.Test ```log ``` ### Description of detection logic ``` IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small. IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small. IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
