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 9.171853384615387 > 7.538575350000001.
IsChangePoint: Marked as a change because one of 10/25/2022 2:56:59 AM, 10/27/2022 12:34:03 AM falls between 10/18/2022 9:26:37 AM and 10/27/2022 12:34:03 AM.
IsRegressionStdDev: Marked as regression because -4.536067139047587 (T) = (0 -8398730.973199025) / Math.Sqrt((465211152579.85406 / (30)) + (323591138695.06525 / (7))) is less than -2.0301079282477414 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (30) + (7) - 2, .025) and -0.1549915532249524 = (7271681.727669953 - 8398730.973199025) / 7271681.727669953 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.
