That would be fine. but, if there is a sixth number that is 5.75, becaust that pushes the total over 5, then I would just like to see:

5.38
5.6
5.6
5.6

So duplicates aren't bad, but they are if they make the total exceed 5. So, as unlikely as it might be, if there were 6 lowest scores all tied, then I wouldn't use any of them.
