calipers are bs and never gives an accurate estimate, not even close. there is no way in earth someone can be 2 bf. andreas mentzer abused the hell out of drugs to get 3%. look what happend to him.
maybe, but that is a different argument for a different day. Bodybuilders use calipers so if one says they are 3%, fine maybe they are not but what they mean is the calipers read 3%
regardless of it actually works out to a true measurement or not, it is still a valid method to go by to make progress, what you guys are arguing is semantics, big deal.
