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 2.1716746313202244 < 2.5993002984665243.
IsChangePoint: Marked as a change because one of 3/11/2022 4:59:21 AM, 6/20/2022 1:54:42 AM, 6/23/2022 3:07:42 AM falls between 6/14/2022 10:05:19 AM and 6/23/2022 3:07:42 AM.
IsImprovementStdDev: Marked as improvement because 28.037667062232355 (T) = (0 -2169.7263965390225) / Math.Sqrt((404785.91147036967 / (299)) + (5621.5978341768305 / (12))) is greater than 1.9676708853560316 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (12) - 2, .975) and 0.35551374188895535 = (3366.5983862842577 - 2169.7263965390225) / 3366.5983862842577 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
