Hello, I dunno if it helps but....
I am sitting with 456 since august and my friend is a very good Chinese astrologist. Based on her predictions I have applied for PNP back in September. She said back then (early in Sept), that there are no chances for this endeavor to work out due to some inner policy or whatever and I won't be selected until January and even then the chances are not that big and that with PNP my chances are a bit better. I know people can laugh at me, but I have posted this back in Sept too.
So, if she has any PNP prospects she should go with it without a doubt because I seriously doubt it will ever drop now below 457-458
