I have not read Mr Jones' work on this. However from what I am reading here I do not really see a discrepancy. I have not gathered he said "All" targets hit by a single pellet would be broken. Obviously as targets are found unbroken with one or more holes all are not broken. Also obviously a perfect score was not registered on that round.
As I understand he stated that having looked at a large number of patterns & considering the number of perfect scores posted some number of targets "Must" have been broken by a single pellet. Some targets remaining unbroken by a single pellet "Does Not" prove that none were. As yet I have seen no evidence that his synopsis is in fact in error.
