Description of detection logic
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 196.7454220779221 > 156.83800762773058.
IsChangePoint: Marked as a change because one of 2/9/2023 1:41:04 PM, 2/16/2023 5:39:51 AM falls between 2/7/2023 3:56:56 PM and 2/16/2023 5:39:51 AM.
