You say that your wife has been after the fragments about 4x as long as you, or put 4x more time into getting them
So really whilst you have recieved 0 .. in the same rough time she would have received 2.5
Not as game breaking as you put it, now maybe if you put the same amount of time into getting them it might be seen as unfair by some but 2.5 .. not a lot tbh
