It will be interesting to watch this progress over the season.

I can see the principle, Its pretty obvious.
though I think some of the calulations may need adjusting from, -1 to 0 for the Bulls
Unless I have the factors wrong

Bulls :Starting points being in Cat B................................................ -2

Bulls 12 -Catalans 34.
Bulls no points for a loss, but no deduction for loosing against Cat A team........0
Catalans no points for beating a Cat B team

Castleford 12 - Bulls 20
Bulls no points for beating a Cat B team..................................................0
Castleford -2 points for loosing against a Cat B team

Bulls 16 -Wigan 54
Bulls no points for a loss, but no deduction for loosing against a Cat A team......0
Wigan no p[oints for winning against a Cat B team

Wakefield 18 - Bulls 36
Bulls no points for winning against a Cat B team.........................................0
Wakefield -2 points for loosing against a Cat B team

Bulls 10 - Warrington 23
Bulls no points for a loss..........................................................................0
Warrington no points for a win against a Cat B team

Hull KR 24 - Bulls 36
Bulls no points for winning against a Cat B team..........................................0
Hull KR 0 points for loosing against a Cat B team .

Bulls 12 - Saints 8
Bulls 2 points for winning against a Cat A team............................................2
Saints -2 points for loosing against a Cat B team

Bulls total ................................................................................0

but we are showing -1 according to Mission. So Mission means start the season not each game with +2 or -2 and then points awarded as he says, plus if its an A team minus if its a B team.

whatever the precise scoring system, and I am sure Mission will clarify and look at the reason for the odd one point difference, simply dividing into A and B teams is starting to be informative. As people have pointed out, St Helens have played 5 in group B and lost two of them, and their next three games are against A teams, no wonder changes were made. Hull have only played 2 of the A teams likewise Wakefield. on results so far Huddersfield are deservedly on top.

just spotted something. Mission, why do Huddersfield have 4 points more than Wigan when theres only one game v B difference? Hudds should get nothing as they should have beaten them, Wigan get 2 deducted so difference should be 2. any chance of a matrix to explain, columns: win draw loss, rows what happens when A plays A A plays B B plays A B plays B?

The extra -1 is to take into account we have to play an extra game against group A opposition to some other teams (Leeds at millenium magic). All teams playing group A opposition at MM get -1 points, all teams playing group B opposition at MM get +1 points.

To explain it another way, if every team won all their remaining matches against the group B teams and lost all their remaining matches against group A teams, this is how the table would end up. As af says, the table will become closer to the actual table as time progresses, and when there are no more matches to play it will end up the same. What it does at this stage is illustrate that taking the relative difficulty of the games played into account, Bradford further ahead of Salford, but not as far ahead of Hull KR, as the Super League table would suggest.

apologies, missed the MM adjustment, so got my head back around it. The big adjustments to this are "upsets" in terms of your designated A and B teams as shown by Saints. If as you say everybody wins against group B and loses against A then that is how the table would end up. I can see some peoples problems with that hypothetical situation, as in reality 2 B teams cannot both win the same game.

as I may have said before, I agree with the principle of weighting opposition for difficulty, just not sure about the weighting you have used - but even less sure about an alternative! So maybe an update each time the Bulls and those near us in the table do not perform as assumed.

Yes, the assumption is (and therefore the accuracy of the prediction depends on) that you would expect any group A team to beat any group B team, and a group B team beating a group A team would be termed an 'upset'.
