The error CJD made was to not take all the ratings out of the same amount as he did for the last set of rates. The way it is done at this point is unfair. An anology: would you like it if you took a test at school, got a higher score than somebody else, but ended up with a lower grade because their score was taken out of a lower total than yours was?
My basic message is that for fairness all scores much be taken out of the same total.
