I suspect that it's a combination of wishful thinking and acclimation. I haven't noticed any significant changes in mine that I've owned (and used) for a few years. You can open up the calculator and slightly over-flex the keys a bit to loosen up the springs/legs, but I don't really recommend doing this, as I've had a number of the plastic legs in my DM42 break even without it. I've had to epoxy at least 3 or 4 broken legs in mine. Not too difficult if only one leg on a key is broken, but if both break, good luck getting the key glued in the proper position...
