The numbers derived form the doe mortality study are just as meaningful as the reproduction stats you love to use so often. In other words, neither one can be accepted blindly without considering the possible sampling problems. Once again, you have proven that you are so set on your agenda that you will jump on potentially flawed data if it fits but you have a cow when someone turns that strategy around on you.
If the numbers from the doe mortality were as meaningful as the reproduction stats, why did the PGC change the way the way they marked the does they were tracking. The answer is because they knew there was a problem with their methodology. But, their has been no change in the way they collect data from road killed does ,except to include does that are lactating as does that have been bred.
