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 87.31729157713795 < 108.02994545548901.
IsChangePoint: Marked as a change because one of 2/26/2022 3:32:05 AM, 4/20/2022 8:23:28 AM, 4/27/2022 8:46:50 AM falls between 4/19/2022 6:32:34 PM and 4/27/2022 8:46:50 AM.
IsImprovementStdDev: Marked as improvement because 2.562874062321932 (T) = (0 -98110.7185378316) / Math.Sqrt((183167520.50564802 / (299)) + (157355252.18686616 / (25))) is greater than 1.9673585853226652 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (25) - 2, .975) and 0.06424117987149829 = (104846.15953110514 - 98110.7185378316) / 104846.15953110514 is greater than 0.05.
