Nice idea Matt, you may have something there  

What if as happens now and had Matt has stated do we work it if your overall score is in the minus  
Could we say if that happens award the points instead but as SCO put it cut down the amount the Gamball is worth if it happens to be your in the minus score ? Eg 6 for a correct result and 12 for correct score in this scenario?

Yeah that was the main problem but the thought was if the Gamball was to reward overall predicting then a minus score wouldn't have many correct predictions amongst it. 
It would only really be a reward to those who got at least 3 right predictions and more of a reward to anyone who got say 5 or 6 right.
Even 6 points CR and 12 points CS would take 3 or 6 of the other matches right to get that number of points
