I see temp rating thrown around more than burnt popcorn at a b-movie, my question is; how do they come up with this rating?

Will it keep an Arizonian alive at this temp or do you need to be a Shug wearing a onesie made of down filled fleece?

I said it was 55*, but last Saturday night it got down to 48*f and I stayed plenty warm wearing a couple layers, on a foam pad with a fleece blanket.

I'm aware that 48* is no where near 20*, and that this is also very subjective, but i'd just like some feedback before I bust out the thread injector and build some quilts with 5 inches of loft.
