in one way You are a 100% correct. which makes its error .021 thou per ft. expressed that way but consider this, with the shim under the digital level and its reading showing 0.2deg then with the shim taken out it reads 0.1 (both directions)how far from 0.2 did it move?

If for example it just shaves off 0.01 to register its 0.1 reading that would be close to 040 thou per ft, expressed another way 7/16" over ten feet.

i am not a perfectionist dont get me wrong, but its inherent flaws makes it useless in a machine shop. i am hoping a new person to our hobby absorbs this little tutorial on levels.
