I would like to see McCallum's chart though if anyone has a link?
Casey also added at what B/F %'s to take the readings at (at roughly 8 to 10% body fat) .
So this would be at the start of cutting generally for a bber that dose 2 shows a year, 1 spring and 1 fall were you don't put on a lot of fat between shows. If you do 1 show a year and have a heavy bulk it would be a few months in.
On average 99% of people under estimate there B/F by a good 2-3%. If you do the fames 7 Point pinch test. It will come up with a reading on average 2% lower than your true B/F %. Electric tests like the hand held and stand on's any water and sodium changes day to day will majorly effect the reading seen as it is testing the current flow threw the water, fat and muscle tissue. Junior High Science teaches us that.
The tank dunk test is the ONLY 99% ACCURATE test.
