course with categories and calculations in the gradebook creates after grading an assignment (qucik grading) for one student (only two students in this course) thousands of entries in mdl_grades_grade for users that are not participants of the course - got 116000 entries for the course in the table for only two students - should have beean about 45 entries.
The grading is I think because of these entries very slow and not really useable...
I hope someone can help me!
