Seems likely that your pay records went to computer first and Service record entries later. I'd find it unlikely that local commands had compter access. Between 1973 and 1993 while on active sea duty in the Navy my records were kept on paper. These were sent off for entry elsewhere. We did no compuer record keeping on personell locally. The computers we had ran combat systems and maintenance records. It wasn't until a few years ago that the Naval Hospital finished going to a computer system (meaning you can actually read a MD's notes). Yes the Fiscal records did hit a computer but only after reaching the Cleveland Finance Center. The mid 80's we started getting a monthly pay statement breaking down our pay from Cleveland. Otherwise everything was on paper one way or another. So the liklihood that a failed paper trail existed in the President's case is quite high. Ever had you Military Medial records lost? Try getting a copy back of those. Get erroneous entriees that needed correction (such as duty station entries I was never near)? That will take some time to fix. Bottom line is even if you had a computer a person still enters data. Garbage into a computer still equals garbage out.
