Bush's missing National Guard payroll records have miraculously been found!

Like records released earlier by the White House, the newly released computerized payroll records show no indication Bush drilled with the Alabama unit during July, August and September of 1972. Pay records covering all of 1972, released previously, also indicated no guard service for Bush during those three months.

But, further on in this WaPo story, we're told these records "do not give any new information toward determining whether Bush kept his National Guard commitments during 1972, when he transferred to the Alabama National Guard unit so he could work on the U.S. Senate campaign of a family friend." Hmm. For months, various folks have been saying that the payroll records would prove whether or not Bush served, which is what made their absence all the more suspicious. Now we have the payroll records, indicating that, indeed, Bush was not paid during the months in question. How is that not informative? What am I missing?
