That information there is worth very little. The data from 4 of the 8 of those bulls came from the reportings from 1 herd. One that specializes in EPD engineering at that. I haven't looked at the numbers but I would wager that very few offspring, maybe a handful?, have been reported out of each of them. It's more of a 'first mover advantage' type deal: Because essentially no carcass data has been reported on the majority of the population, those individual bulls who do have
some carcass data reported, by default, become the trait leaders. I may run a 12 minute mile but if I'm the only person entered in the race, then not only am I the fastest, but I'm the champ!

Does anyone know how many scans and/or kills are needed to get a bull to the .5 acc minimum? Is a kill the equivalent of 7 or 8 scans?
You can't look at like that. Depending on the accuracy of the references used in your contemporary group, it might take 1 calf to get .5 or it might take 100. It's a sliding scale: The higher the level of accuracy the reference sires in the contemporary group are, the less calves it will take. Inversely, the lower the accuracy of the reference sire, the more calves it will take.
