```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 6.695488891847749 < 8.424729018831327.
IsChangePoint: Marked as a change because one of 1/17/2023 5:52:57 PM, 2/9/2023 12:40:40 PM, 2/14/2023 10:45:34 AM falls between 2/5/2023 7:19:43 PM and 2/14/2023 10:45:34 AM.
