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 21.29256809978281 < 23.366907154654008.
IsChangePoint: Marked as a change because one of 10/13/2022 5:08:18 AM, 11/23/2022 1:02:40 AM, 11/29/2022 1:43:29 AM falls between 11/20/2022 12:28:28 PM and 11/29/2022 1:43:29 AM.
IsImprovementStdDev: Marked as improvement because 15.895798116304203 (T) = (0 -21.681503459881068) / Math.Sqrt((0.5504423037288633 / (299)) + (0.144274346321204 / (26))) is greater than 1.967335607330539 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (26) - 2, .975) and 0.05928848772179335 = (23.04798354957196 - 21.681503459881068) / 23.04798354957196 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
