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.
IsRegressionWindowed: Marked as regression because 6.420741366606145 > 4.836528073337696.
IsChangePoint: Marked as a change because one of 9/22/2022 3:11:11 PM, 9/27/2022 9:53:04 AM, 10/13/2022 2:25:23 AM, 10/19/2022 4:51:05 PM falls between 10/7/2022 4:12:34 PM and 10/19/2022 4:51:05 PM.
IsRegressionStdDev: Marked as regression because -5.198383363662658 (T) = (0 -6.154681728810027) / Math.Sqrt((0.3509297891141544 / (16)) + (0.07696060942759915 / (22))) is less than -2.028094000977961 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (16) + (22) - 2, .025) and -0.15566009228205294 = (5.3256850953955945 - 6.154681728810027) / 5.3256850953955945 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
