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 185.10440075859154 > 113.25698283021671.
IsChangePoint: Marked as a change because one of 3/30/2022 6:37:35 PM, 4/5/2022 2:02:34 AM falls between 3/26/2022 9:07:40 PM and 4/5/2022 2:02:34 AM.
