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 59.40722926209776 < 62.08484598172883.
IsChangePoint: Marked as a change because one of 2/2/2022 9:06:26 AM, 2/3/2022 8:57:20 PM, 3/17/2022 11:30:59 AM, 3/22/2022 12:26:23 PM falls between 3/13/2022 11:50:20 AM and 3/22/2022 12:26:23 PM.
IsImprovementStdDev: Marked as improvement because 23.74012028080874 (T) = (0 -59.413733386384536) / Math.Sqrt((21.935990614271685 / (299)) + (0.00021026775222749748 / (3))) is greater than 1.9679030112610798 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (3) - 2, .975) and 0.09770057875057603 = (65.84702592861434 - 59.413733386384536) / 65.84702592861434 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
