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.
IsRegressionWindowed: Marked as regression because 6.752904475043029 > 5.7600755166264.
IsChangePoint: Marked as a change because one of 8/29/2022 8:26:03 AM, 9/6/2022 1:06:44 PM, 9/9/2022 3:12:19 AM, 9/23/2022 1:16:35 AM, 9/29/2022 7:42:19 AM, 10/19/2022 7:27:15 PM, 10/26/2022 7:11:30 AM, 11/2/2022 9:35:40 AM, 11/7/2022 4:10:19 PM, 11/14/2022 7:25:10 PM falls between 11/5/2022 10:22:58 PM and 11/14/2022 7:25:10 PM.
