What do GBUauto and GBVauto entries indicate in the LOG table?

GBUauto and GBVauto entries reflect automatic system recalculation of a student's overall gradebook score — not manual data entry. These updates are logged when the system recalculates an overall score and detects a difference from the stored value, which occurs during gradebook data loads such as when the Scores by Class or Scores by Student pages are accessed.
