Are you asking for clarification on how to log your work?

The rules state: Therefore, you may work ahead or fall behind and catch up later, so long as you don't go more than 72 hours without logging a completed assignment.

Where "...logging a completed assignment" means to use the Entry Form to report that you have completed an assignment. Logging an assignment is the equivalent of turning in your assignment to the teacher in school, except that, since many of our Preppers prefer to keep their work private while in progress, you're on the honor system. You don't actually turn in your work. You just report, formally, through the Entry Form, that you did the work.

We have no way of knowing when the work was completed. We can only track when you reported that you finished an assignment.

A spreadsheet is used to track your entries. The 72-hour calculation is automated. Since your bio block says you work in IT, I'll explain the tech. The spreadsheet subtracts each of your time stamps from the previous time stamp and compares it to 72 hours using a compound function:

Time Elapsed = (the timestamp of the current post) - (the timestamp of the previous post)

IF (Time Elapsed) > 72 hours, THEN (Exceeded 72) = the timestamp of the previous post + 72 hours
