'date added in the last' and frequency of folder monitoring

Hello,
Fantastic app, thank you Mr Noodle !
I created a rule whereby added (ie downloaded) pdf files in the download folder are automatically opened in my PDF app, PDF Expert.
My problem is that I want to open the PDF files only once. I observed that Hazel keeps reloading the files into PDF Expert, probably corresponding to the time delay of the Hazel folder monitoring cycle.
How do I have Hazel open the files only once:
- I was going to set a specific time frame: 'added in the last' but to do so, I would need to know the Hazel flder monitoring cycle frequency so the time delay is neither too short nor too long.
- or is there a simpler way to indicate 'open once only' ?
thanks very much
