Hey guys, I still do not understand how you can get usable results from numbers that only say how the dog is doing in comparison with the rest of the population. I am not questioning the results, mind, I would just like to know what they mean.
I mean, if, theoretically, the whole population of US vlcaks was HD A(0/0), wouldn't the percentiles be of no real value? I mean in population of healthy animals, even the lowest-score is still healthy. And in reverse, if most of animals was D or E, than if one was in great percentile, it could still be just a C or D dog...

So do the result contain also some other numbers, that reflect the absolute values, not relative?
