Repeatability is used to determine the length of the test observation period. There is NO need to repeat measurements.

The 'quasi-' recognizes that it is very unlikely that there would be absolutely no variation with time. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
