Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 12/4/2022 6:53:17 AM, 12/13/2022 2:17:54 AM falls between 12/4/2022 6:53:17 AM and 12/13/2022 2:17:54 AM.
IsRegressionStdDev: Marked as regression because -73.5803483320907 (T) = (0 -118.88074229211672) / Math.Sqrt((1.0214611233495723 / (3)) + (2.8914996808653433 / (6))) is less than -2.3646242515927898 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (3) + (6) - 2, .025) and -1.2794473057903666 = (52.15331891644518 - 118.88074229211672) / 52.15331891644518 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
