71GE2cL Value is weighted average of results listed as follows:
71GE3cL 20.082 ms {I+71-70} (2014De19, in averaging uncertainty increased to
71GE4cL 0.105 ms by evaluators to account for possible systematic
71GE5cL uncertainties); 20.48 ms {I18} (1980Jo11,Ge(Li) with NaI anti-Compton);
71GEBcL 21.5 ms {I4} (1974Bu14,neutron activation of Ge(Li) detector);

71GEIcL in the averaging procedure, as these appear to be outliers.
