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 6.789579067730634 > 4.6191408849201805.
IsChangePoint: Marked as a change because one of 11/16/2022 4:37:16 PM, 11/18/2022 7:31:41 AM, 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.

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.
