A friend of mine now deceased, had a very large family of Finish spitz. she bred when she wanted to keep two, and as her litters were small, usually got just two. she showed whatever she had, unless it was really awful!
She won numerous CCs, but never 3 with the same dog, as she always fielded a team of six, or sometimes only 4 at Open shows. she was extremely knowlegeable, and did judge at CC level, but saw it more as a responsibility, and never judged my breed of which she certtainly knew a lot, having had at least one for many years, and knew a lot more than some of the judges giving us CCs.
I will never judge, as I have a visual disability, and haven't the money! I have only just had the good fortune to breed a champion in my 3rd genertation, but othersd make up their first dog, or breed one in their first litter more by luck than judgement. I don't hink it neccesarily corelates that a person who has top winners will judge well. though I suppose someone who has bred and shown real horrors for a long time is unlikely to have a good eye either!
