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 144.5475957573862 < 176.3328717693238.
IsChangePoint: Marked as a change because one of 2/25/2022 8:42:58 PM, 2/28/2022 8:13:22 PM, 3/3/2022 4:26:18 PM, 3/8/2022 2:08:40 PM falls between 2/27/2022 3:52:50 PM and 3/8/2022 2:08:40 PM.
IsImprovementStdDev: Marked as improvement because 8.470626690977657 (T) = (0 -156.99041071968514) / Math.Sqrt((57.795164754176234 / (299)) + (30.702196482634047 / (24))) is greater than 1.967381707010986 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (24) - 2, .975) and 0.06145178200459314 = (167.2694143034998 - 156.99041071968514) / 167.2694143034998 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
