Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 1.0783099 < 1.176594839423077.
IsChangePoint: Marked as a change because one of 1/27/2023 3:43:27 AM, 2/2/2023 2:17:49 AM falls between 1/24/2023 11:54:43 AM and 2/2/2023 2:17:49 AM.
IsImprovementStdDev: Marked as improvement because 11.048452513333782 (T) = (0 -1113.190206424314) / Math.Sqrt((519.9093590989374 / (299)) + (2378.97296941525 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.10301788362777992 = (1241.039465676899 - 1113.190206424314) / 1241.039465676899 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
