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 1.9915830184028922 < 2.2583693911734812.
IsChangePoint: Marked as a change because one of 6/26/2022 6:11:06 PM, 6/30/2022 12:21:07 PM falls between 6/21/2022 9:29:01 PM and 6/30/2022 12:21:07 PM.
IsImprovementStdDev: Marked as improvement because 11.723203700578452 (T) = (0 -1921.2497816060247) / Math.Sqrt((29621.546067752082 / (196)) + (13855.618242528171 / (12))) is greater than 1.9715466694451473 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (196) + (12) - 2, .975) and 0.18065903723012827 = (2344.8721215048613 - 1921.2497816060247) / 2344.8721215048613 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
