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 71.8079338126019 < 83.21151300347786.
IsChangePoint: Marked as a change because one of 1/28/2022 4:34:00 PM, 2/2/2022 8:22:24 PM falls between 1/25/2022 5:49:56 AM and 2/2/2022 8:22:24 PM.
IsImprovementStdDev: Marked as improvement because 14.24658926942749 (T) = (0 -75.74271574532719) / Math.Sqrt((9.43953819246514 / (299)) + (14.624381993997646 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.14734166275841667 = (88.83126152306306 - 75.74271574532719) / 88.83126152306306 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
