I remember this question arose earlier in the season.
To put it simply:
I use all the Correct Score odds quoted by Bet 365.
Everyone in the competition is deducted one YAP each game, regardless of whether they make a prediction or not.
Anyone who correctly predicts the score receives the quoted odds plus his deducted YAP back.
As only predictions are accepted for quoted odds, any other predictions are ignored.
I previously stated that any forecasts that are not quoted are a wasted YAP, except in the unlikely event that one of these not-quoted predictions turns out to be the correct score. Then you get your YAP back. This was not correct. You lose a YAP regardless of the outcome for a non-quoted prediction.
I’ll have a rethink in time for next season. Perhaps 200/1 for any bets not quoted, or then again, maybe deduct 2 YAPs for making a non-quoted prediction in the first place.
