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 1.4571775881313367 < 416.9135474537037.
IsChangePoint: Marked as a change because one of 2/14/2022 7:55:17 PM, 2/22/2022 12:12:47 AM falls between 2/13/2022 12:11:49 PM and 2/22/2022 12:12:47 AM.
IsImprovementStdDev: Marked as improvement because 537.729651827715 (T) = (0 -1475.3906807101262) / Math.Sqrt((14675226.920884196 / (22)) + (506.24639273261437 / (45))) is greater than 1.9971379083914016 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (45) - 2, .975) and 0.9966518739197195 = (440661.62543872005 - 1475.3906807101262) / 440661.62543872005 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
