Hi, mymy, not sure what you mean by "weight," but you should get four small score hops: one for each card going over 12 months old, and one for each inq that resulted in you getting each card.
When one of my cards turned 1 recently, I got points for age on the first of that month, but I didn't get the points for the inq no longer counting until the exact day of the month that it had originally hit.
Happy birthday!
