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 57.35437116856663 < 59.28344583868849.
IsChangePoint: Marked as a change because one of 3/31/2022 1:45:25 PM, 4/16/2022 5:36:25 PM, 5/17/2022 3:30:02 AM, 5/20/2022 10:18:01 PM, 5/23/2022 7:50:08 PM, 5/25/2022 1:42:32 AM, 5/30/2022 12:57:05 PM, 5/31/2022 8:51:40 AM falls between 5/22/2022 6:37:49 PM and 5/31/2022 8:51:40 AM.
