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 11.698769186174355 < 16.339155838720647.
IsChangePoint: Marked as a change because one of 3/4/2022 6:17:23 AM, 3/7/2022 10:45:01 PM, 3/15/2022 4:36:24 AM falls between 3/6/2022 4:27:35 PM and 3/15/2022 4:36:24 AM.
IsImprovementStdDev: Marked as improvement because 9.329981542780262 (T) = (0 -12.612002274585238) / Math.Sqrt((2.601894295242495 / (200)) + (1.2171930333813394 / (37))) is greater than 1.9701100622679821 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (200) + (37) - 2, .975) and 0.13681619273493748 = (14.611027417839875 - 12.612002274585238) / 14.611027417839875 is greater than 0.05.
