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.
IsRegressionWindowed: Marked as regression because 93.72826836778536 > 91.51960243883491.
IsChangePoint: Marked as a change because one of 10/22/2022 11:54:51 PM, 10/25/2022 2:56:59 AM falls between 10/16/2022 1:15:28 PM and 10/25/2022 2:56:59 AM.
