I do understand the difference between entry and extension, just read my post.
That is why I tell you might never need an extension, so I am not misunderstanding anything.
I just wanted to explain there are situations you might need 2 extensions within 1 year.
When you want to stay 190 days, then leave for 5 days and then again want to stay over 180 days.
In that case you need the first extention before you leave, and only use 10 days. When you get back in after 5 days you will get 180 day entry, after that you will need extention again, only 195 days after the first extension.
Maybe you should plan your trips outside a bit different, but a real digital nomad plans his trips according his business and not according dates of entries or extensions expiring.
