Lumia 920 Durable but Very Scratchable

I'm a little bit concerned with the real life durability of mine and my wife's Lumia 920. I've seen all the crazy torture tests and am utterly confused as to how mine and my wife's phone are being so scratched up with light usage in light of these results.

My phone got a scratch on the back right down the side from my wedding ring while taking it out of my pocket. My screen got a deep scratch right in the middle from I don't know what. My wife's phone also has some light scratches on the back and on the screen.

I suppose I'm especially disappointed in the gorilla glass 2. What is the deal with all the scratching?
