Also, as Chaim pointed out in a email response to a different query, I have taken the absolute differences rather than the difference from the value one would have to pay.
 
Other than that it seems okay ;-)

I set these values in an Excel sheet and found the difference to all the possible values.
I did the same with the sevenths values in the given answer.
If you then total the differences my values come out just over $10 better.
Am I doing something wrong?
