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 38.80313055040986 > 36.41515371063089.
IsChangePoint: Marked as a change because one of 1/11/2023 2:37:52 AM, 1/17/2023 6:49:05 AM falls between 1/8/2023 8:00:22 AM and 1/17/2023 6:49:05 AM.
