[Wien] EFG: theory Vs experiment for a case

In principle there is no objection. If it is a sufficiently clean experiment (good statistics, not too many different sites, sufficiently strong EFGs,...) then TDPAC can get eta with an error bar better than 0.1.

Have a look at http://dx.doi.org/10.1021/acs.jpcc.6b06127 . The literature history is in this sentence on page 2:

"A rule of thumb of 10−20% is sometimes quoted [18,19,21,24] yet the origin of this number is
unclear and certainly not based on rigorous testing."

and the detailed analysis for the error bar on the EFG for 111Cd in hcp-Cd is in the section 'error budget' on page 4. The resulting error bars are listed in the last column of Tab. 1.
