Like all the rules this one is totally at the discretion of the organiser (who is completely open to bribes). It is very unlikely to be implemented for a 5 - 0 win, whereas will be ruthlessly administered if I feel that someone is trying to exploit the generous points scoring system (this comes under the "don't disrespect the competition" heading). Many of the other prediction competitions only award a point for the first goal scorer to prevent this. By the way I've gone for 4 - 0 so that will definitely be acceptable! The rule, although possible under a different clause, did exist last time I ran this competition. It was hastily added after someone tried to submit a ridiculous score purely to enter a record number of scorers. It is probably for the best that you change your prediction Beth (although I know you are not in the slightest concerned about winning). I do have a complete set of rules for this. If I get bored enough I'll write post them up, there maybe some that surprise you.
As requested changing my prediction....(However I will morally claim the whole seasons trophy if QPR lose 9-10 with my original scorers scoring) QPR 2 (Austen and AJ) v Charlton 4 ( Kermorgant 2 Church 2. )
