Hello... Indeed may if I were a native English speaker it would have been easier to understand each other... Anyway, I think we are on the right track
.OK--the small strips are cut based on the belief that the amount of PE on the entire length can be accurately estimated by measuring the amount on a small portion of it? In other words, if the whole strip contains x grams of PE, and we cut a strip equivalent to 1/10 of the whole, then the assumption is that the amount of PE on the whole strip is equal to 10 times what's found on the cut sample? If this is the case, are you sure that the amount of PE hanging off is linear (uniform) across the big strip, or is that what you're trying to determine?
