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 1.1315733462546538 < 1.1463189235670763.
IsChangePoint: Marked as a change because one of 3/18/2022 1:59:24 AM, 5/12/2022 5:35:05 PM, 5/18/2022 4:10:31 AM falls between 5/9/2022 3:38:36 PM and 5/18/2022 4:10:31 AM.
IsImprovementStdDev: Marked as improvement because 28.09258040498529 (T) = (0 -1111.565372644305) / Math.Sqrt((4151.098144654106 / (299)) + (377.28789672937535 / (22))) is greater than 1.9674283869023508 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (22) - 2, .975) and 0.12341316679067585 = (1268.060767664838 - 1111.565372644305) / 1268.060767664838 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
