The fact remains that the stallions that are full brothers are genetically the same have not served the same mares so you cannot compare results with progeny.
I am guessing Monique that you are standing Christian Fire? if so he just does not get sent mares of any quality which will reflect in progeny. As for saying breeding with better stallions you pay $9k for a good stallion or say $6k but its hypothetical on your belief as if a sire has never served any mares how can you predict his progeny.
The only relevance is what opportunity does he receive? any sire must get his chance with decent or quality mares to measure his worth.
