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 263.8527205128205 < 372.0641311119792.
IsChangePoint: Marked as a change because one of 3/17/2022 6:54:53 PM, 3/22/2022 2:14:22 AM falls between 3/13/2022 11:50:20 AM and 3/22/2022 2:14:22 AM.
IsImprovementStdDev: Marked as improvement because 48.925446194930835 (T) = (0 -277203.7755722266) / Math.Sqrt((180848.52741868005 / (299)) + (98557802.1843423 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.29229489041798384 = (391693.90162513923 - 277203.7755722266) / 391693.90162513923 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
