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.
That looks intentional. Custom metrics need more time to collect and evaluate the underlying data, so the hourly option isn’t available like it is for the standard metrics. I don’t know of a setting that enables it, so for a test under 24 hours I’d stick with a standard metric and use the custom metric for longer experiments.
