I've had no issues with RT as long as I have the data set right. It is extremely consistent and has helped my become more consistent in my stringing processes.
Right now RT is showing a reading of +/- .1 lb from job to job. It does read a littler higher than reference right off the stringer. I average 3-4% 24hr tension loss vs. right off stringer.
Been using it now for over a year and anytime I've had issues it turned out to be user error.
