I'm using the Path Experiment element in Marketing Cloud Next Edition and want to set up A/B testing for my email sends. I noticed that when I select "Standard Metrics" for performance, I can set the test duration in hours, days, or weeks. However, when I switch to "Custom Performance Metrics," the "hours" option is no longer available, and I can only choose days or weeks.
Is this the expected behavior? Is there a way to use a shorter (hourly) test duration when using custom metrics, or is this limitation by design? Any best practices or workarounds would be appreciated.
