That is me putting it in embellished words of amusement instead of saying that the software ran numbers through the dongle if it was present so that the logic on the dongle would correct it but if it was not present it would allow the run and save except the altered numbers would have a unnoticeably tiny miscalculation that would accumulate over the numerous edits and saves during the project duration.

Because I assumed that people would put it together themselves. Which apparently most people did. But some people still need everything spelled out for them. Ironically those that credit themselves more intelligent than everybody else.
