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 8.865383362022623 > 7.347480226005509.
IsChangePoint: Marked as a change because one of 1/3/2023 6:29:42 AM, 1/10/2023 7:48:18 AM falls between 1/1/2023 3:57:25 AM and 1/10/2023 7:48:18 AM.
