This method was developed as a simpler calculation alternative to difficult and unwieldy calculation methods such as the transfer function method and the method. Error when using the CLTD/CLF/SCL method tends to be less than twenty percent over and less than ten percent under. History [ ] After its introduction in the 1979 handbook, research continued on increasing the accuracy of the CLTD/CLF method.

Research completed in 1984 revealed some factors which were not accounted for in the original publication of the method; these findings were a result of the research project 359. In 1988 Research Project 472 worked to correct these oversights with the introduction of a classification system for walls, roofs, and zones. Additionally, a weighting factor database was generated to help correct for previous inaccuracies. Casio G Shock Mt G Neon Illuminator Manual.
