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 391.0855613616762 < 417.6104771496231.
IsChangePoint: Marked as a change because one of 1/28/2022 6:30:08 PM, 2/1/2022 2:18:14 AM falls between 1/23/2022 1:32:42 AM and 2/1/2022 2:18:14 AM.
IsImprovementStdDev: Marked as improvement because 64.86402545065125 (T) = (0 -392.07952187016843) / Math.Sqrt((26.18769300911998 / (299)) + (8.087209284291491 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.1130034658809831 = (442.0305004456301 - 392.07952187016843) / 442.0305004456301 is greater than 0.05.
