What are the requirements for the DTV bank statement balances for Thailand visa applications?

For the DTV is the 500,000 baht requirement just for your current balance? Or do all 3 bank statements you submit need to be above 500,000 baht?

My closing statements are:

August $20,000 (650k baht)

Sept $15,300 (498k baht) at today's exchange rate

Oct $18,000 (580k baht)

Nov $19,000 ($610k baht)

Am I going to be rejected because of my September statement?

Are there certain consulates that are bad and good for this?
