Carb class and EFI together

With the EFI and Carb class combined in 08, heres a thought. Most if not all EFI engines were dynoed by the factory and ued SAE J 1349 correction factor which is 29.234 baro and 77 Deg carb air. Most Carb engines used SAE J607 which is 29.92 baro and 92 deg carb air. So what is means is that a carb engine would be about 5% lower with the J 1349 so which horspower will be used. This looks like to me the carb HP need to be reduced by about 5 %..
