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 87.08482230527075 < 834.7543641887218.
IsChangePoint: Marked as a change because one of 4/9/2022 5:43:54 AM, 4/14/2022 3:36:10 AM falls between 4/5/2022 1:54:35 PM and 4/14/2022 3:36:10 AM.
IsImprovementStdDev: Marked as improvement because 6803.124817400822 (T) = (0 -87.15883858583138) / Math.Sqrt((2.255789788962656 / (299)) + (0.09631016381053494 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.90089697479033 = (879.4770734942903 - 87.15883858583138) / 879.4770734942903 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
