It is amazing how the numbers work out to 40 percent on a per-chip basis. However, I believe this is a coincidence because the 40 percent reduced package indicates the comparison was made as a reduction to 6 grams compared to the national average of 10 grams. To add another perspective, nutrition people usually care about fat per calories. The regular is 47 percent fat compared to the reduced fat of 38 percent. This is a 17 percent reduction. But thanks for sharing. I will keep an eye out for this issue for other nutrition labels too! Ranma Saotome:

The reduced fat version has 23 chips per 1 ounce serving, with 6 grams of fat per serving, so each chip has 0.26 grams of fat. The regular version has 19 chips per 1 ounce serving, with 8 grams of fat per serving, so each chip has 0.42 grams of fat. This is about a 40% reduction, and I bet this is actually how they are calculating it.
