Yes, I know all of that, but on the application it asks you when you believe you will enter and when you believe you will exit. Like you said, you either have to exit before 180 days or 360 days, if you get an extension. That would count as your next exit and is what you write on your application. You wouldn’t stay in Thailand for a full 5 years, so wouldn’t put a date five years later as your exit date.
