```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.
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 13.089494764527748 > 11.772108646550445.
IsChangePoint: Marked as a change because one of 2/15/2023 8:48:29 AM, 2/21/2023 10:35:27 PM, 3/10/2023 8:06:53 PM, 3/14/2023 10:43:28 AM falls between 3/5/2023 5:50:49 PM and 3/14/2023 10:43:28 AM.
