let's see if I can't clear it up.
The RULE is if you're in thailand when a 90 day report is due you report. If you're not you don't
The WINDOW to report is person is 2 weeks before down to 1 weeks after your due date.
That has nothing to do with your due date, and if you're IN the country you report.
There is no "I had other things to do" so didn't report option. You have from the 13th of Nov until you fly out to report.
As people pointed out, when you return your 90 day report will be due 89 days from the date you stamp in AND if you don't report this time there is a good chance the officer will see your previous 90 day report was due BEFORE you exited the country and you didn't do it and they can fine you 2000baht for failure to file a 90 day report on time and then let you file your next report
