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 288.99214920700007 < 296.89447237001065.
IsChangePoint: Marked as a change because one of 3/15/2022 12:53:39 AM, 3/22/2022 2:14:22 AM falls between 3/13/2022 11:50:20 AM and 3/22/2022 2:14:22 AM.
IsImprovementStdDev: Marked as improvement because 23.091118886713875 (T) = (0 -278.7647055055054) / Math.Sqrt((29.10755783080123 / (299)) + (108.78146102038833 / (35))) is greater than 1.9671350567190904 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (35) - 2, .975) and 0.1291491382201918 = (320.1061372733534 - 278.7647055055054) / 320.1061372733534 is greater than 0.05.
