As Tod says there’s no official limit entering by visa exempt by air, BUT they will for sure start question you (ask for onward ticket, fund proof, accommodation booking etc), if you keep try entering on visa exempt for multiple times a year. Also it can depend on what passport you hold, prior entry history, which airport (some are more strict than others). Btw langborder runs are generally a “big red flag” for any immigration officer, so don’t have to many of these in your entry history. At the end of the day there’s no fully correct answer, as it is totally up to the single immigration officer that you hand in your passport to 😉

ha ha awesome 👏🏻😉

Technically yes, but in reality no! Expect after a few 2-3 borderuns per yeah to get denied more entries, or at least getting told apply for right visa, as you clearly with that many month in Thailand aren’t a regular tourist, which the Visa exempt are there for 😉
