From what I have seen in your picture, the difference is explainable. It seems that I can stretch my pinky more so that the pinky and thumb are almost in one line instead beeing in a angle (so more towards 180 degree instead 150). If you would raise your hand wrist instead putting flat on the ruler, maybe you could stretch your pinky also more (that should give at least some millimeters more - not that this is of any importance however ... )?
