The Smart campaign sent the email to 20% of the leads, didn't do anything with the other 80%, and then was done doing everything it was told to do in the flow. It wont stagger out sends over 5 days with the logic in the screenshot alone. Especially since the campaign was set to a lead can only go through the Flow once. Even though 80% of the leads did not get an email, they still technically went through the Flow, so they wouldn't qualify for subsequent runs of that campaign.
You may just want to break the qualified leads into five random lists first, then target each list individually over the 5 days.
Thanks for your answer! I think I get why then.
Do I have to split it into 5 random lists...? is there another way to only run the campaign 1/5 of the list on each scheduled run?
My ultimate goal is to keep adding people to one list, then the campaign will pick up the list and run it through
