If you max out the time given, the chances are even smaller that they'll let you back in without a proper visa.
The "10 times" is more a hyperbole statement.
Get a Multi Entry Tourist Visa, or even a DTV Soft Power visa ( or workcation, if you are a remote worker )
the Multi Entry Tourist Visa will get you to 9 months, the DTV will get you to 5 years, but limited to 180 days per entry, that can be extended, but that's a hassle to do compared to leaving and coming back,
Thailand doesn't want people to live here on tourist visas and visa exemptions.
