    Is percentage calculation fair.

    Looking at the results this season, and our position at 2 on the ladder. we know how the percentage is worked out, but all the same the Swans won by 80 and 60 points, whereas the Bulldogs won by 65 and 57 points, but they are still about 52 percentage points up on us. Just doesnt seem a very fair system

    If we had only 74 points scored against us in the first two games, as Footscray have, we'd be miles ahead on top. System is ultimately fair. Like democracy, it sure is the best of the alternatives

      Of course it's fair.
      If we score 300 pts and our opposition scored 200 pts then the opposition player pretty damn well, despite the 100 pt margin.

        It's a question of whether you like apples or oranges. Either percentage which is a division of a for and against by Subtraction.

        Personally I like the percentage in afl more than the for and against in the rugby league. The percentage reflects both the offensive and defensive aspects of the game a little more equally than a pure subtraction.

        For example if at the end of the season for arguments sake two clubs have a F/A of 2500/2000 and the other club 2000/1500. The both have the same points difference but the latter club is rewarded with a higher percentage because they've demonstrated a better defence. To me that means they've been harder to beat so should be ahead of the team that leaks goals.

          I wonder what the statistical variance is of % at the end of the year. Many ladder positions are decided by a % or two which just comes down to luck with weather and fickle bounce

            i understand why it's used - sports like footy and cricket use a quotient based ladder due to different ground dimensions (and weather having a greater impact on the scoring)

            Personally i think it favours defensive teams too heavily - but i'm not sure there's a better solution.

              Would you still think it favours defensive teams too if at the end of the season we beat west coast into 4th place on percentage because even though they've scored more than us they also had a weaker defence ( conceding over 100 points despite beating Brisbane could be the example that makes them have a lower percentage)

                Bonus point system, ala Rugby? Score over a certain amount and get a point?

                    And if you play ever other week on a carpet under a roof, vs playing in torrential wind and rain?

                      This applies also to the OP question.
                      If you're playing at Edihad every week with a closed roof, scores (and margins) will be higher.
                      Then you could also factor in the biggest inequity, playing lowly teams twice.
                      eg: Teams who played Essendon twice this year celebrated when the finding was released - maybe not such a walk in the park though.
                      Then the AFL can't get it right based on the previous year. Freo may well turn out to be the team you want to play twice...

                        I'm not advocating a change but if options were to be considered the AFL might favour a system which reinforces its current focus on encouraging attacking football.

                        Cricket Australia has done this in the Sheffield Shield competition by allocating points for aggressive scoring in the first innings. This is somewhat analogous to the bonus point idea that RogueSwan has mentioned. The current percentage calculation in principle does favour defensive football.

                        Weather, venue, schedule may influence results and percentage/points, but that is true under any system I think.

                          First step is to even out the comp.

                          I know others will disagree, but it needs an overhaul.
                          The main season needs to be each team plays each other once. 17 rounds of H & A
                          Easiest way to cover the missing 5 rounds is to extend the finals somehow, which I am not opposed to.

                          Other scenarios have been proposed for finals for the top 6, middle 6 and bottom 6. Some of which sound great.
                          But then we get back to 'changing the game', which so many are opposed to here.

                              Simple solution: bonus point for scoring more than the average for that ground, with a weighting for whether you are the home team or not, another weighting whether there is open or closed roof, and then another weighting for based on the distance traveled to get there, an additional weighting on how often you play at that ground and a final weighting based on the opposition teams rolling, last 23 rounds, ladder position.
                              It is so obvious, I'm surprised you couldn't see it liz?
