Campbell 20 torso breadths such as acromial, transverse chest, biiliocristal, etc. are obtained with straight branches. AP Chest, and some head measurements are made using the AP Extension or Branch Pointers with olive tips. These are exactly 10 cm each (and can be calibrated using the adjustable screw and lock nut). Thus the caliper reading from AP branch tips will be 20 cm too large (easily corrected by subtracting 20 cm constant in the data entry program or spread sheet).
