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 35.76447299878451 < 46.72998902001652.
IsChangePoint: Marked as a change because one of 8/4/2022 3:21:43 PM, 8/11/2022 10:02:44 AM falls between 8/2/2022 9:32:02 PM and 8/11/2022 10:02:44 AM.
