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 149.5143396226415 < 159.26941253789178.
IsChangePoint: Marked as a change because one of 2/12/2022 1:03:18 PM, 2/18/2022 5:51:51 PM, 2/25/2022 11:02:46 PM, 4/19/2022 4:39:14 PM, 4/26/2022 6:18:08 AM falls between 4/17/2022 3:25:40 PM and 4/26/2022 6:18:08 AM.
IsImprovementStdDev: Marked as improvement because 52.83211866541415 (T) = (0 -149269.8694675039) / Math.Sqrt((21591781.35690124 / (299)) + (953125.275250663 / (35))) is greater than 1.9671350567190904 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (35) - 2, .975) and 0.10040709242855844 = (165930.46500386015 - 149269.8694675039) / 165930.46500386015 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
