These technologies offer varying levels of accuracy and precision. Problems such as spamming reduces the accuracy and precision of results. That yields to double precision floating point accuracy. This is a comparison of differences in precision, not accuracy. The surveyor must be able to distinguish between accuracy and precision. See also Accuracy and precision and its talk. It has analog tolerances that affect its timing accuracy. It emphasizes the accuracy and density of measurements. For some scientific work timing of the utmost accuracy is essential. This provides generally a better numerical accuracy. For greater accuracy but lower generality component testing is used. The measurements are usually performed in triplicate for increased accuracy. There are also differences in the accuracy of calculations. Several methods of varying accuracy and complexity exist. It was intended for high accuracy range shooting.
