I've already explained it quite clearly. Multiple times. My point in contrasting the amount of lead per chip if you assume my interpretation is correct vs if you assume your interpretation is correct is that your formula results in a nonsensical amount of lead in each chip. We all know that leaded chips weigh about 2 grams more than non-leaded chips (8-9g/ea vs 10-12g/ea). If the formula for leaded chips makes up a mere 1.4% of the total weight (as in your interpretation) then removing all the lead from the chips would only change the weight by 1.4%. But we know this can't be true since leaded chips weigh ~22% more than unleaded chips (11g/9g = 1.22). However, using the correct (and obvious) interpretation of the formula, the math makes perfect sense.
The ingredients by volume are more informative than the ingredients by weight, though both are useful. You can calculate the volume using the formula Vsg=m/(SG∗998.2) where Vsg is the volume from specific gravity (m^3), m is the mass in kg, and SG is the specific gravity or density (g/cm^3).
Here is how the math works out for the correct interpretation of the formula. Notice all the numbers make perfect sense by both weight and volume.

Here is how the math works out for your incorrect interpretation of the formula. Notice the numbers do not make sense whatsoever as your imaginary chips would be effectively pillows with some dust on them having 43.8% of the volume as cotton.

Hope that helps. Though I don't hold out much hope.
