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 25.582088141025643 > 20.891587583097515.
IsChangePoint: Marked as a change because one of 6/22/2022 6:53:40 PM, 6/28/2022 10:14:54 AM falls between 6/19/2022 8:44:36 PM and 6/28/2022 10:14:54 AM.
