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 18.077737148102816 < 24.23265905969031.
IsChangePoint: Marked as a change because one of 3/23/2022 3:49:50 AM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsImprovementStdDev: Marked as improvement because 77.03482007098077 (T) = (0 -17905.155113194687) / Math.Sqrt((2202771.4968716307 / (299)) + (137893.37192625843 / (38))) is greater than 1.967070609662329 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (38) - 2, .975) and 0.3108930626633502 = (25983.12996586112 - 17905.155113194687) / 25983.12996586112 is greater than 0.05.
