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 39.92729605742583 < 41.50383661894745.
IsChangePoint: Marked as a change because one of 1/28/2022 4:34:00 PM, 4/12/2022 3:59:36 PM, 4/14/2022 3:36:10 AM falls between 4/5/2022 1:54:35 PM and 4/14/2022 3:36:10 AM.
