Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 149.39291522108846 > 122.01453583107035.
IsChangePoint: Marked as a change because one of 12/15/2021 12:53:06 PM, 1/5/2022 6:46:20 PM falls between 12/6/2021 2:46:54 PM and 1/5/2022 6:46:20 PM.
IsRegressionStdDev: Marked as regression because -31.908252014298096 (T) = (0 -143030.70530083627) / Math.Sqrt((8578565.28640735 / (46)) + (30845166.263695396 / (66))) is less than -1.9817652821320164 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (46) + (66) - 2, .025) and -0.22009095803972706 = (117229.54289460367 - 143030.70530083627) / 117229.54289460367 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
