How does the Thailand Elite 5-year visa work with entry stamps and duration?

The Thailand Elite 5-year visa allows for unlimited exits and entries, with each entry granting a new yearly stamp. If the visa holder exits every four months, they will receive a new year entry stamp each time they return. However, there is clarification needed on whether exiting just before the 5-year expiry would extend the visa duration, as some users noted it could stretch effectively to around 6 years, although this would not confer additional Elite privileges.
