Is this amount of dust excessive?

I own a 2012 800S LE. We went on a 30 mile ride last weekend in what I considered to be a typical Utah ride "dust-wise." What are your opinions on the amount of dust in the air box? This was the first time I used the Outerwear pre-filter so I was expecting my OEM filter to be a lot less dusty than this. It looks to me like the Outerwear pre-filter sure stopped a lot of the dust.

I would just like your opinions as I’m thinking that is way too much dust in there.
