Ok, anybody use the calipers by accu-measure? I've had them now for about 2 months or so, measure my b.f. at least once a weekthe way they say to. I've measured an average of 2mm on the scale, that's 3.5% b.f. according to the chart. I measured this all through cutting phase, and even now for about 3 weeks into post cutting, bulking phase. Am I doing something wrong here?
