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 515.8583895096629 < 557.6802727613956.
IsChangePoint: Marked as a change because one of 7/7/2022 2:16:02 PM, 7/14/2022 8:56:55 AM falls between 7/5/2022 7:51:46 PM and 7/14/2022 8:56:55 AM.
