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 167.34102430555555 > 158.46117698317312.
IsChangePoint: Marked as a change because one of 4/22/2022 6:17:37 AM, 4/26/2022 6:18:08 AM falls between 4/17/2022 3:25:40 PM and 4/26/2022 6:18:08 AM.
