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 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 8/13/2022 2:59:44 AM, 8/18/2022 11:13:04 AM falls between 8/9/2022 9:33:37 PM and 8/18/2022 11:13:04 AM.
IsRegressionStdDev: Marked as regression because -13.301195798386802 (T) = (0 -780924.1216518995) / Math.Sqrt((1816446026.8913484 / (16)) + (2945738217.569549 / (26))) is less than -2.0210753903043583 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (16) + (26) - 2, .025) and -0.3450330993912639 = (580598.4417820876 - 780924.1216518995) / 580598.4417820876 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.
