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 49.1680785115304 < 50.55404605478208.
IsChangePoint: Marked as a change because one of 6/7/2022 11:31:29 PM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsImprovementStdDev: Marked as improvement because 10.275026807559158 (T) = (0 -48602.90481596941) / Math.Sqrt((711975.7901998487 / (170)) + (947632.9735285057 / (4))) is greater than 1.9738521694944169 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (170) + (4) - 2, .975) and 0.09404244148393182 = (53648.10344491141 - 48602.90481596941) / 53648.10344491141 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
