Deciphering labels

We've been getting a variety of whole wheat bread lately -- I won't give the brand. It's a smidgeon pricey, so I looked over the ingredients to see if this was something I could make myself. (And one in the household is keeping track of nutrition.) If I understand labeling rules, ingredients are supposed to be listed in order of their contribution by weight.

One of the ingredients is "Malted Barely Flour." OK...

The label says a loaf provides 17 serving sizes. Loaves consistently have 15 slices of bread, including the heels.

The loaf is listed as 1 lb. The kitchen scale says 1 lb 3 oz.

I'm not complaining, but has anybody looked at what they are advertising on their label?

Anyhow, the nutrition scaling factor is 1.34.
