Measurements and legs' position
While taking the usual measurements I notices a huge difference between the BPEL measured while laying back with my legs open or with my legs closed. When my legs are closed together, I get about 1 cm less (~ 0.4 inches). Understandable: with open legs one can push the pelvis out more.
How do you measure your BPEL? With closed or open legs? Is there a standard way of taking measurements?
