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 368.9782103689918 < 414.6964149536311.
IsChangePoint: Marked as a change because one of 9/23/2021 3:17:45 PM, 11/17/2021 2:42:53 PM, 11/23/2021 6:42:08 AM falls between 11/14/2021 12:07:47 PM and 11/23/2021 6:42:08 AM.
IsImprovementStdDev: Marked as improvement because 42.80791216688891 (T) = (0 -370.32436932694884) / Math.Sqrt((137.93461115806187 / (299)) + (29.438593657636797 / (27))) is greater than 1.9673127716992511 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (27) - 2, .975) and 0.12586765889708296 = (423.6479442685993 - 370.32436932694884) / 423.6479442685993 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
