Not doing it like that. in 2022 I entered 8 times visa exempt. In 2019 14 times visa exempt. I was working in Singapore and the Netherlands. I never had an extension. I would leave after 20 -25 days, and come back after about a week. If you going to an extension and leave for 2 days that is abusing
Ian if you take care of of your return entries you can manage you mission successfully. After staying 60 days leave the country for 5-7 days via air. Don’t do land border entries and return immediately. I did this for 18 months immediately after Covid never had a problem or a question. That does not guarantee you will be ok, but you are most likely to be fine
