In particular , with regard to the method Hybrid Estimation of Risks ( Ref A7 Ed 2007), which is no longer provided in the Appendices, but in the rules of section 6.5 , has been corrected in the description of the frequency , the value 6 with the value 5, since this value previously created inconsistencies and in some cases not tabulated values in the calculation of Estimated Risk .
