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 1.5832809947142008 < 4.031142534709341.
IsChangePoint: Marked as a change because one of 1/25/2022 5:49:56 AM, 3/2/2022 3:17:47 PM, 3/8/2022 2:08:40 PM falls between 2/27/2022 3:52:50 PM and 3/8/2022 2:08:40 PM.
IsImprovementStdDev: Marked as improvement because 61.42065228104022 (T) = (0 -1.6312348557929477) / Math.Sqrt((0.2771687457176209 / (299)) + (0.028706422315709197 / (31))) is greater than 1.9672228266464409 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (31) - 2, .975) and 0.61844045580437 = (4.275177703212149 - 1.6312348557929477) / 4.275177703212149 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
