3 Questions - reload renew periodically

[nicck]

Hi

I have created 2 scripts, 1st script is scraping data into file and 2nd script is reading data from that same file and deletes that line after using it.
I want to make sure that 2nd script gets the new data that is being added by 1st script into the same file.
So i am using both the options reload periodically and renew periodically with 60,000 milliseconds gap to solve this situation.

Now I have 3 questions :

1. Is this way correct that i mentioned above ?
2. what is the difference between reload periodically and renew periodically, i read the tooltip help text when i hover over them but didn't understand it fully.
3. The delay is in milliseconds for reload and renew periodically ?

Thanks
