Thanks for the response Dave. I was wondering if we could do something similar. Ideally we'd like to have two grades which the course leader could compare and give the final grade. I think your solution is very workable though.
There appears to be a mdl_grade_grades_history table now (Moodle 2.6 onwards?) which on paper should produce a view of the changes to each grade. This would be invaluable to a second marking process. Unfortunately when I trailed the db table it didn't accurately capture the grade changes. Looks very promising for the future though.
