Seriously, what's wrong with key fragment drop rate?

Every month was fine except July and August. July: crafted 1 key and then got only 2 out of 3 fragments in around 27 days! August: got 2 out of 3 fragments and they stopped dropping. I know it gets rarer with each ey crafted but first and second keys used to be acquired quite quickly.
