It is only priceless to a biased PGC supporter. Researchers reveal their bias over and over again in how they interpret the results of their research and Kroll is a prime example. Instead of investigating why some bucks develop slower than others he concluded there is no difference between the average 1.5 spike and the average 1.5 Y ,at 4.5 years. That is the same as claiming there are no inferior buck and that is simply not true.
