Description of detection logic

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.
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 92.68256689935374 < 106.79147739779275.
IsChangePoint: Marked as a change because one of 3/10/2023 8:06:53 PM, 4/12/2023 8:39:35 PM, 4/25/2023 1:57:48 PM, 5/2/2023 9:04:55 PM falls between 4/24/2023 8:06:00 AM and 5/2/2023 9:04:55 PM.
