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 654.2512993640573 > 577.664298021476.
IsChangePoint: Marked as a change because one of 5/27/2022 3:44:45 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -7.579016658164447 (T) = (0 -677.5733587457601) / Math.Sqrt((1212.8122349029154 / (19)) + (2671.502121975659 / (21))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (19) + (21) - 2, .025) and -0.18288034027384517 = (572.8164850460673 - 677.5733587457601) / 572.8164850460673 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.
