Finger thing is weird. My fingers don’t have constant length to the tenth of a millimeter, and holding my hand in the copier for a long time was uncomfortable enough that the fingers probably bent at least two millimeters. So if you really need tenths of a millimeter accuracy, disregard the one that has a result for the right hand and says ‘nope’ for the left hand.
