I have set up a grade with a scale: unseat, sat, outstanding, which I understand for the purposes of averaging translate to 0,1,2. I thought I could use a calculation to change that to 75,85,95 by doing 75+grade*10. But it seems to me that calculations on individual grade items cannot incorporate the selves, but only other grade items. That's because on the item number list, the grade itself is not given an item number nor a way for me to assign one.
