that is a very low number, the lowest ive personally actually heard anyone have. i dont know why they would send you another short form after just a year. my number is just a little higher than yours and i got the short form in june with a 3 year review date, which i guess means nothing now. its really strange that yours went to 7 years this time yet they sent you one a year later. maybe they are sending everone one ever year now? who knows.
