decaying behavior score - decaying for each interaction - expert challenge

I'm new to Marketo here so someone more seasoned might be able to answer this better then myself.

But you could use any one of the inactivity Filters for the Smart List, and then the "flow" could be something like Change score -5 and then just sceduel it to run every week or so?

Would that do what you're looking to do?

So i guess just create a "inactivity program" and run it however often you want with the filters you would like to track. 

Here's what i'm seeing...

 

Hope this helps. 

There are a couple of thoughts here:

1. Trigger Score - first interaction gets +15, then a wait step, then it checks if any activity occured, if Not, then -5, then it waits again,
 

The check is conducted by a smart list that looks for Inactivity Filters as Stephen suggested. I see some issues with this setup though.

2. Batch Campaign
Each day you run this and it pulls in the folks who had that interaction. It waits, then asks Campaign 2 to deduct scores if needed. Batch campaign keeps waiting and keeps calling the deduct campaign.

One of the issues is that you can't have this go on forever unless you set it up as a loop, where the Batch calls Deduct Campaign 2 and then Campaign 2 calls Batch or something. I suppose this might work, but I'd be worried you'd break the scores eventually.
