To get a good idea of a dogs quality you need to show it over a season or so to maturity, under breed specialists and experienced all rounder judges.
At 7 months I doubt you have had a chance to go to many shows yet, and if they were open shows the judges may not have been breed experts or may have been judges in training.
Also as you say your bitches coat and behaviour may well have a bearing 'on the day'.
What the judges should be looking for is a dog that in their opinion as closely as possible meets the breed standard.
