There is a big difference on the scores different european countries give to a same xray.
I mean xray that scores A1 in one country could score C in a another country.
I know this because for example in Finland they are pretty strict so some people go over to neighbouring country to get their dogs xrayed to get better scores.
This is of course cheating the system but it happens.
I'm not sure you can compare the score numbers in UK and europe(I have seen some webpages giving corresponding UK score/european score).
For example in my breed if you look at the UK scores most dogs would score A or B(=healthy) hardly any Cs, Ds or Es...
I would not imagine this is because of UK dogs having better hips than the dogs in Europe but how the xrays are scored/numbers matched to Letter.
Of course there has to be something to give an idea of what the letter stands for so breeders in UK have an idea but I do not believe it to be as straight forward as A1 =0-4 etc...
My humble opinion only :)
