If luck-deprivation were a recognised condition Investors surely qualified for government assistance on the strength of this weekend's results.

The most painful piece of misfortune was the Blues' victory by 18 points over Port Adelaide on Sunday where the difference between the behind after the siren that we got, and the goal after the siren that we wanted represented a 4.7c swing in the Recommended Portfolio price. In other lamentable games, Melbourne went within a kick of narrowing the Tigers' lead by enough to land our SuperMargin wager and Sydney collapsed inexplicably in the last 10 minutes of their game with the Dockers to put paid to our Line and SuperMargin wagers, all of which looked very promising until the capitulation unfolded.

In summary the Head-to-Head Fund collected on its only wager to climb by 1.8c, the Line Fund was successful in only 2 of its 7 wagers to slump by 8c, and the Margin Fund lost all 16 of its wagers to drop 20c. As a result, the Recommended Portfolio fell 6.3c to finish down 9.3c on the season.

TIPSTERS AND PREDICTORS

The draw prevented a clean sweep by the Head-to-Head Tipsters, and upset victories by Brisbane and Collingwood lowered most scores even further, reducing the best-credentialled Tipsters to 6.5 from 9 performances this week. The only Tipster to do better was Home Sweet Home, which managed 7.5 for the week but which remains in last position. At the other end of this same leaderboard, Combo_NN2 continues to enjoy a 3 tip lead over the rest of the field.

MAFL Margin Predictors have a new leader, however, with RSMP_Weighted's 21.01 mean absolute prediction error (MAPE) for the round allowing it to squeeze past RSMP_Simple, whose 21.93 MAPE was, in turn, sufficient for it to retain second place ahead of Combo_7. In another week of, on average, extraordinarily predictable margins the worst MAPE of the round was 28.14 points per game, recorded by Combo_NN2. The round's best performance belonged to ProPred_7, which recorded a MAPE of 19.67 points per game.

On line betting both of the RSMP-based Predictors are still tipping at a rate above 60%.

There's no change in the order of the Head-to-Head Probability Predictors this week, with the Bookmaker-derived Predictors still holding down the first three places and with the Risk-Equalising variant performing best. ProPred still leads the pack of Predictors that aren't (as) directly Bookmaker-derived, and WinPred retains last place.

The Line Fund algorithm performed slightly better this week than last week but still turned in a negative probability score for the round leaving it solidly in red ink for the season to date.

SUPERMARGIN PERFORMANCES

ProPred_7 recorded the best set of results in SuperMargin wagering this week, selecting the correct bucket in 2 games and being in error by a single bucket in 2 more. The two Win-based and four H2H-based Predictors were all almost equally as impressive, selecting the correct bucket in 1 game and missing by a single bucket in 3 more.

Combo_NN2 was another nominee for the round's "Close But No Cigar" award, also missing by a single bucket in 3 games.
