Adelaide have retained number 1 ranking on MoSSBODS and MoSHBODS after their 24-point and 9- Scoring Shot victory over Hawthorn.

After last weekend's inauspicious start, it's a relief to report that all three forecaster families performed far better this week.

It usually takes a few weeks of a new season to iron out the main bugs in updated and new scripts (and why, exactly, are bugs always 'ironed'?) and to get into the swing of knowing what data goes where. This season has been no exception.

If you pootle around the MoS website - and, by pootle, I mean search - you'll find a number of posts using the terms 'overround' and 'vig' (or 'vigorish'). Today I want to provide a quick refresher on what those terms mean and why they should be important to you if you ever think about placing wagers of your own.

This week, the TAB's over/under markets went up well before Centrebet's, and Centrebet released theirs over an extended period, which means that the data in the table below spans an atypically long timespan since each market has been recorded as close to its opening as I was able.

It's hard to find a dissenting voice this week amongst the MoS Head-to-Head Tipsters, with even Home Sweet Home tipping against the favourites in only three games.

We noted last year that Adelaide, as far as the MoS Team Rating Systems were concerned, were very unlucky not to progress further in the competition. Their big win over GWS this weekend only served to reinforce that view.

From an accuracy point-of-view, the first round of 2017 was a poor one for the MoS Head-to-Head Tipsters, though that's probably to be expected when only four favourites and an equal-favourite prevail.

We'll need to review our approach to the over/under market this season, I think, since, if this week is a guide, opening markets will be less generously priced.

I'm flipping the order of the sections in the weekly Wagers & Tips blog this year, providing the tips and predictions before the wagers. I think that everyone who comes here is interested in the tips, but only a subset are interested in the wagers as well. And, populism is all the rage right now ...

Today, a couple of new voices share their analysis here on MoS: sport lovers Declan Walpole and PhD student, Robert Nguyen, who've teamed up to have crack at rating the AFLW Teams after two full rounds, and using their ratings to predict the results for the upcoming round.

If history chooses to repeat one of the themes of 2016, please let it be the largely unembarrassing performances of MoS' bookmaker-input free Tipsters and Predictors, and the resultant profitability of the MoS Funds. (I'd wish for something grander on the global stage, but I suspect that's just courting disappointment.)
