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 1.9524201822916667 < 3.2471728180902777.
IsChangePoint: Marked as a change because one of 4/6/2022 2:58:43 AM, 4/11/2022 8:24:09 AM falls between 4/2/2022 3:48:06 PM and 4/11/2022 8:24:09 AM.
IsImprovementStdDev: Marked as improvement because 24.966819807229562 (T) = (0 -1955539.352841666) / Math.Sqrt((708570755680.1926 / (270)) + (116299016.17988726 / (17))) is greater than 1.968322603028609 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (270) + (17) - 2, .975) and 0.39573208024326395 = (3236212.429792599 - 1955539.352841666) / 3236212.429792599 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
