There are three games this week where MoSHPlay’s forecast margins differs from MoSHBODS’ by more than a goal:

• Collingwood v Richmond: MoSHPlay Pies by 11; MoSHBODS Tigers by 6

• Port Adelaide v GWS: MoSHPlay Port by 5; MoSHBODS Giants by 3

• Sydney v Geelong: MoSHPlay Cats by 14; MoSHBODS Cats by 7

Apart from the Pies v Tigers, and Port v Giants games just listed, MoSHPlay is also tipping, contrary to MoSHBODS, the Hawks to beat the Lions, and the Dees to beat the Saints (in all cases, pending the finalisation of teams).

There are likely to be some big moves on the MoS Leaderboards this week.

In aggregate, there’s close to accord between the MoS twins and the bookmakers this week, though again some differences that exceed 6 points in size.

The average expected margin for Round 19, according to the bookmakers early in the week, is just 14.1 points per game, eclipsing Round 18, and recording the new lowest average for any round since Round 14, and the lowest for any nine-game round since Round 10. It’s also the lowest average for a Round 19 across the period we’re analysing, and almost seven points below the all-season average for Round 19s across that same period.

That low average has come about because seven of the nine games have an expected margin of less than 15 points, and an eighth has an expected margin of just over 4 goals. But for the 39.5 point margin in the Suns v Dons game, we might well have had a record low for the season.

Brisbane Lions retained top spot on MoSSBODS this week, ahead of GWS and Richmond, and moved up one place on MoSHBODS into 3rd, behind GWS and Richmond

In other moves on MoSSBODS, Hawthorn climbed 4 places into 6th, St Kilda climbed 3 places into 14th, North Melbourne dropped 3 places into 8th, and the Western Bulldogs plummeted 6 places into 12th. No other team moved by more than 2 places.

On MoSHBODS, no team at all moved by more than 2 places.

Not a great round for MoSHPlay, in any of its forms, which allowed, for starters, Bookie Knows Best, the RSMP twins, and ENS_Linear to join it atop the Head-to-Head Tipsters Leaderboard. Those five are now on 99 from 153 (65%).

There are three games this week where MoSHPlay’s forecast margins differs from MoSHBODS’ by more than a goal:

• Richmond v Port Adelaide: MoSHPlay Port by 1; MoSHBODS Tigers by 14

• Geelong v Hawthorn: MoSHPlay Cats by 19; MoSHBODS Cats by 10

• Carlton v Gold Coast: MoSHPlay Blues by 35; MoSHBODS Blues by 27

That Port Adelaide call from MoSHPlay looks to be a brave one, but is consistent with MoSHPlay’s relatively low rating of the Richmond list (which led to the ill-fated call that they’d lose to the Giants last week). That Tigers v Port game is the only one where MoSHPlay and MoSSBODS are tipping different winners.

This week looks very similar to last week, with the MoS twins, on average, forecasting slightly lower totals than the bookmakers, though still differing by non-trivial amounts in a number of games.

The average expected margin for Round 18 is just 16.3 points per game, the lowest for any round since Round 14, and the lowest for any nine-game round since Round 10. It’s also the second-lowest average for a Round 18 across the period we’re analysing, and nine points below the all-season average for Round 18s across that same period.

MoSSBODS and MoSHBODS both elevated Brisbane Lions this week, MoSSBODS by one spot into 1st, and MoSHBODS by four spots into 4th.

MoSSBODS, in fact, shuffled a large number of teams in its top half, which left GWS in 2nd, behind the Lions, Richmond in 3rd, and Geelong in 4th. MoSHBODS, in contrast, left its Top 3 unchanged as GWS, Geelong and then Richmond.

In a round that, if anything, made it less certain which team is currently the best in the competition, just six of nine favourites won.

There’s a little more disagreement between MoSHPlay and MoSHBODS this week, but not much, with the margin forecasts differing only by amounts ranging from about 1 to 10 points, the largest of them being:

• Geelong v St Kilda: MoSHPlay Cats by 50; MoSHBODS Cats by 40

• Gold Coast v Adelaide: MoSHPlay Crows by 46; MoSHBODS Crows by 37

• Port Adelaide v Brisbane Lions: MoSHPlay Port by 26; MoSHBODS Port by 19

In only one game are MoSHPlay and MoSHBODS tipping different winners - the Essendon v North Melbourne game, which MoSHPlay has Essendon winning by 2, and MoSHBODS has North Melbourne winning by 4.

In something of a return to a milder version of the early parts of the season this week, the MoS twins are forecasting generally lower scores than the bookmakers, but overall only by a few points.

For the third week in a row the average bookmaker handicap for the round is above the season average, but it is, at least, under 20 points per game for the first time since Round 14, and for the first nine-game round since Round 10.

GWS, despite losing to Brisbane Lions, held onto 1st place on MoSSBODS and MoSHBODS this week, though it now has only a 1.1 Scoring Shot lead over the Lions on MoSSBODS, and a 4.6 points lead over the Cats on MoSHBODS.

MoSSBODS still has North Melbourne in 3rd, while MoSHBODS has this week rocketed Richmond into that position.

All of the Tipsters at the top of the Head-to-Head Tipster Leaderboard tipped 5 from 9 winners this week, which left MoSHPlay_Marg as leader, now on 90 from 135 (67%), still two tips clear of Bookie Knows Best and the RSMP twins.

MoSHPlay is, again this week, in close agreement with MoSHBODS about the likely margins in each of the nine contests, differing by a goal or more in only two of them:

• Carlton v Melbourne: MoSHPlay Melbourne by 14; MoSHBODS Melbourne by 6

• Western Bulldogs v Geelong: MoSHPlay Geelong by 19; MoSHBODS Geelong by 13

In all nine contests, MoSHPlay and MoSHBODS are currently selecting the same team to win, although MoSHPlay has Adelaide winning by only one point in their clash with Port Adelaide.

It’s another week of broad, overall agreement between the MoS twins and the bookmakers, though the twins have tended towards very slightly lower total scores.

Back to nine games for this week’s round, which always seems a much larger than 50% increase when you’re doing the data input.

No game this week has a bookmaker handicap of less than two goals, and only one has a handicap of much more than four, which has made for an all-game average of just over 20 points per game.

GWS, despite losing to Essendon this week, generated 21 scoring shots to the Dons’ 17, which was just enough to see MoSSBODS give them a pass mark and leave their Combined Rating essentially unchanged. MoSHBODS was less forgiving, however, and did drop the Giants’ Rating, but not enough to tip them out of 1st place.

Both Systems still have the same Top 2 then of GWS and Geelong, but MoSSBODS has the Roos in 3rd while MoSHBODS has retained Collingwood in that position.

There were no dramatic moves on the MoS Leaderboards this week, as the Head-to-Head Tipsters were separated by just one tip, the Margin Predictors by just 1.7 points per game, and the Head-to-Head Probability Predictors turned in very similar, slightly negative log probability scores.
