That sounds like really thin paper, Joe. :^) Truth be told, common copy paper measures about .003" and business card stock is .01". (actually more like .004" and .013 ) . A factor of 10 is a big difference. But I agree that we don't need to, or hardly can, level to the thousandths of an inch. When working with any level, be sure to rotate it 180 degrees to see if you are getting the same bubble position each time. If you are not, there is something wrong with the level's reading.
