Maybe your measurements are in increments of 0.01. Correction for Sag. This is the second volume of a proposed six volume series presenting a full opening repertoire for White, based on 1.d4. The measurement increment of 0.1 may be too small in this case as it is just about equal to the smallest effective measurement increment. These errors, caused by the imperfections in the construction or adjustment of instruments, affect all measurements alike. Natural Errors These are caused due to variations in nature i.e., variations in wind, temperature, humidity, refraction, gravity and magnetic field of the earth. PDF Errors in Survey Measurements It should be free from obstructions throughout the whole of its length.
