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.

IsImprovementWindowed:Marked as improvement because 65.408925 < 73.30702233333332.
IsChangePoint: Marked as a change because one of 2/26/2022 10:27:55 AM, 3/16/2022 5:02:20 PM, 3/31/2022 1:23:38 AM, 4/5/2022 2:02:34 AM falls between 3/26/2022 9:07:40 PM and 4/5/2022 2:02:34 AM.
IsImprovementStdDev: Marked as improvement because 19.248246680053825 (T) = (0 -66237093.552317254) / Math.Sqrt((12246070304354.23 / (299)) + (4524631752363.647 / (23))) is greater than 1.9674049737480528 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (23) - 2, .975) and 0.12409220612704845 = (75621080.22745234 - 66237093.552317254) / 75621080.22745234 is greater than 0.05.
