I would try to time your arrival and the application to the 1-year extension in a manner which places the date for every annual renewed application for the next EOS, into the months December or January. These are months I will spend in Thailand anyways, this would be the middle of my hibernation. For this, I entered Thailand on October 5th on a 90-days Non-Imm-O visa, and the date of my annual extension application thus is unchanged on January 4th since 17 years. I visit Immigration around 1 week before Christmas with all documents required, leaving a gap of two weeks until January 4th, just in case Immigration asks for something I am not prepared for. . . . this timing will have the side effect that if I enter 90 days before the application date, I can do my 90-days report on the same day I apply for the next extension. Plus I always buy a single re-entry permit for the new 1-year extension on that same day
