because unless the imported dogs actual pedigree had repeated animals in the three to 5 generations the kennel club have records for it won't.
Most of my dogs mate select COI result, on the right it will say something along the lines the data used to calculate this is based on up to 16, 17 or 18 generations, but the first 4, 5 or whatever are complete.
Most of our dogs have imports in their pedigrees every couple of generations, even every other generation, with numbers bred so low at present.
