Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 27.17335870265621 < 28.87783003094067.
IsChangePoint: Marked as a change because one of 3/17/2022 6:54:53 PM, 3/30/2022 6:37:35 PM, 4/25/2022 11:05:49 AM, 5/20/2022 9:09:19 PM, 5/24/2022 7:58:36 AM falls between 5/15/2022 6:57:22 PM and 5/24/2022 7:58:36 AM.
