I understand that but the point that I am making is people can get confused when they read this is a visa renewal. Visa's are not renewed, you apply for a new visa. This sounds like an application for extension of stay after the the date you are permitted to stay on the O-A visa expires.
Is not another option "Or, have an annual income, pension, and money in a Thai bank, which come to a combined total of at least 800,000 Thai Baht."?
I've always been confused about how this works. Does it mean you can have six months deposits of 65,000 Thb and the balance as a lump sum in a Thai bank account?
