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 50.21760873800129 < 1.1646137788764974.
IsChangePoint: Marked as a change because one of 10/26/2022 7:25:48 AM, 11/3/2022 4:18:41 AM falls between 10/25/2022 1:30:53 PM and 11/3/2022 4:18:41 AM.
