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 68.88758023671896 < 127.45877666666667.
IsChangePoint: Marked as a change because one of 2/22/2022 5:41:06 PM, 3/7/2022 6:10:39 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 126.03464779804523 (T) = (0 -69046.52229781116) / Math.Sqrt((112334656.12084311 / (299)) + (50525.15756847023 / (2))) is greater than 1.9679296690655894 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (2) - 2, .975) and 0.536145395901276 = (148853.80394567715 - 69046.52229781116) / 148853.80394567715 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
