I'm the last person I ever thought would be writing about working from home. You can also use the Smart Campaign Settings to ensure a record only runs through the campaign once. You can double-check yourself by creating the smart list logic, viewing the "Schedule" tab, and clicking the "set to affect xx people" hyperlink and viewing their date values for your calculated date filter to ensure your logic is doing what you expect it to. to answer your question, using the "in past 1 day" filter should do the trick for you.

If you use an "in past before" filter you want to combine it with a filter to make sure your date field is not empty. Otherwise, it'll pull in anyone with NULL values for the date field, as well as anyone who actually qualifies based on their date value. So for the example you gave using the two filters together, Marketo would be looking for anyone whose calculated date filter was (2 days before 10/1) or earlier AND in the past day, which would return no results. The "in past before" filter lets you look for any activity before a stated time period. The first example you gave of using a combination of the "in past before 2 days" and "in past 1 day" filters will cause a conflict.
