you only can achieve almost 9 months, if you do a re-entry on the very last day of the visa validity. . . What you did during the 6 months before the visa validity expired - meaning regardless you did 30 days extensions or border runs, it does not matter at all. It has no influence onto the last 60 days admitted stay. And you only will get close to 9 months if an Immigration officer is willing to give you a 30 days extension, or if you get granted a visa-exempt entry before the last 60 days expire. This will be decided at the sole discretion of the immigration officer. Many people are known to have just achieved 8 months out of the METV, and being refused any extensions
