Let's say a campaign is set so that a lead can only run through it once every 30 days.
Then let's say the lead is removed from the flow after spending 10 days in this campaign.
But then let's say we want the lead to re-enter this campaign. Will the lead still have to wait another 20 days before it can be included into the campaign? Or does Marketo "restart" the lead's campaign timer, so to speak, and allow the lead to enter the campaign again after it's been removed.
The main use case here is that we're trying to make sure a lead doesn't enter multiple nurture tracks. However, a lead's nurture track can change depending on how it develops with the sales rep. So we want to allow leads to move in and out freely.
