Trimble ACCESS displays its RTK fixed residuals at 68% or at 95% confidence level?

I know that ACCESS allows user to select the confidence interval (68%, 95% and 99.9%), but I have searched in all Trimble literature about how ACCESS reports by default its RTK error for a fixed position since I have been questioned in several bid specs if it is at 68% (1 sigma) or as it should be at 2 sigmas (95%) for RTK topographic surveys as indicated in the NGS single CORS RTK guidelines.   


Can I configure ACCESS to display the FIXED H/V residuals and RMS at the same time or is it better to have RMS than residuals displayed since the Trimble receiver's precision specs in their data sheets have ±8mm + 1ppm RMS for RTK?
