I think most dogs that become title holders will have won more than just the 3 CC's, there will be quite a number of RCC's etc. People will know which dogs titles have been gained this way, as worthy dogs tend to have a winning track record, not just 3 bit wins.
Problem is I would hope that am on friendly terms with the majority of people in my breed, some of these are those whose opinions I would respect above others, and value a top award from them.
My Jozi was made up by my main mentor (the other had only been alive long enough to see us win our first CC), she went on to win another 9CC's from a mixture of breed specialists (all of whom I am/was friendly with) and all rounders, though none other was as close a friend as the one who gave me her third.
It is not surprising that connections sometimes put dogs up as you tend to be friendly with those whose stock you admire and or have connections with yours and your likely to like their stock.
The alternative is to be mainly judged by non specialists, and we see the effects of that in the generic show dogs that often lack essential breed type winning in other countries, especially the USA where small breed entries mean very few specialist judges.
Maybe using overseas specialists is the answer, but even there, there will be plenty of knowledge of lines and most people deeply involved in breeds know their breed, dogs and the breeders internationally.
