I was reading the monthly newsletter from the Miner Institute and found this resource (even includes pictures of correct and incorrect use of heart girth tape).
If you do not receive the Miner Institute newsletter you might find it useful. The link to the newsletter is HERE.
The link to the the October, 2016 issue with the weight tape article is HERE. Scroll to page three to find the article with pictures.
