Media, that is the form in which information is published, has always been beguiling in its own right. That was certainly the case when computerised loadsheets appeared on the scene. Prior to that the hand written ones had scope for corrections so that "all work must be shown". Hence one could spot a problem offering by its many amendments and thus peruse it with ever greater care.
All that was changed by the "believe me, just see how beautifully tabulated is my printout" replacement that only showed AL5 or whatever. You believed it at your peril, and it was important to quickly grasp the GIGO concept (garbage in equals garbage out). The blunders still abounded, it was that they were less obvious and hence the more deadly.
Caveat Emptor!
