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 24.79683194919235 < 26.99815700226668.
IsChangePoint: Marked as a change because one of 11/17/2021 1:03:18 AM, 11/24/2021 10:47:45 PM falls between 11/16/2021 7:52:31 AM and 11/24/2021 10:47:45 PM.
IsImprovementStdDev: Marked as improvement because 11.357180174536603 (T) = (0 -25.485707984281067) / Math.Sqrt((3.159412685636631 / (299)) + (3.291190768870089 / (39))) is greater than 1.9670493839589689 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (39) - 2, .975) and 0.12074034288393035 = (28.985417195044512 - 25.485707984281067) / 28.985417195044512 is greater than 0.05.
