Just to clarify. Opting out of predicting will win you a point for up to 4 matches if the result goes as expected. However you are excluded from the chance of any bonus points including the one for selecting the correct results in a Round where there is a bonus point to be won for getting all correct. The TDM is a tie-breaker but only as a last resort. The following is an extract from the rules. "The leaderboard shows the total scores of players taking part in this pool. Where required, ties are broken with tie-breaking rules. Unlike on the Global Leaderboard, Bonus Points (BP) are included here. Tie-breaking In the event of points ties on a pool leaderboard, position is allocated on the basis of higher WP total, then higher MP total, then lower TDM. If scores are still tied after these criteria are applied, the players are adjudged to be tied. TDM is Total Distance from Margin: the sum of the differences between a player's margin predictions and the actual margins."
