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.

IsImprovementWindowed:Marked as improvement because 15.451851579259076 < 16.530275577533565.
IsChangePoint: Marked as a change because one of 12/28/2021 4:54:18 AM, 12/28/2021 11:22:34 PM, 1/26/2022 3:56:56 PM, 5/5/2022 4:01:04 PM, 5/9/2022 6:32:22 AM falls between 4/30/2022 6:29:51 PM and 5/9/2022 6:32:22 AM.
IsImprovementStdDev: Marked as improvement because 27.799932550727092 (T) = (0 -15.217498112387965) / Math.Sqrt((1.064695307596387 / (299)) + (0.024341015721564645 / (11))) is greater than 1.9676960046166507 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (11) - 2, .975) and 0.12189183396640056 = (17.329867436633872 - 15.217498112387965) / 17.329867436633872 is greater than 0.05.
