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 28.055650388291514 < 28.94324036499252.
IsChangePoint: Marked as a change because one of 8/18/2022 5:47:38 AM, 9/22/2022 3:11:11 PM, 9/27/2022 11:22:50 AM, 10/17/2022 12:47:34 PM, 10/25/2022 2:56:59 AM falls between 10/16/2022 1:15:28 PM and 10/25/2022 2:56:59 AM.
