No, not regardless. You need 800k for 2 months before applying for the extension then for 3 months after. For the rest of the year it cannot fall below 400k. Meanwhile you are sending 65k each and every month by international transfer starting before the first extension is granted to switch to this method for subsequent extension applications.
Visas are valid from the date of issue usually for 90 days (unless it's a long term Visa) so don't apply too soon as it will be valid for entry usually for just 90 days from the date of issue
