just would like to update,

a call to MPC said a 2 month grey period will be given for me (~FEB) to make it to silver, meanwhile my account will be downgraded to Green.
But I ended up softlanded to silver with only 16000 club miles without even getting into the grey period (~end of Dec).
I have a revenue J ticket (JFK-HKG) in January though, but still interesting.
