What Documents Are Required for a Third 12-Month Extension of Stay for a Non-Imm O Retirement Visa in Thailand?

Have just added to "Files" section the actual docs I needed to provide yesterday at CW for a third 12 month extension of stay for my Non Imm "O" retirement visa. It included 3 new forms (Acknowledgement Overstay Penalties, Acknowledgement Rules for granting of extension, and a statement of guarantee by someone that I do actually live where I have lived for the last 27 months) These new forms may have been required since during the last year I increased my deposit from THB400K to THB800K. Nothing else varied but they were concerned I had changed the terms of the current extension without approval and may have had a bank balance of less than the THB400K, and may have used a different bank book for the previous extension.
