Current Situation
Club	F	A	%
NMFC North Melbourne	1893	1759	107.6
MELB Melbourne	1842	1758	104.8
Potential 5 goal margin scorelines
Melbourne	31	61	91	121	151	181	211
Carlton	1	31	61	91	121	151	181
New percentage	106.48	106.37	106.27	106.17	106.07	105.97	105.88

 

Quite clearly, the higher the score - the lower the percentage gain.

Excellent and clear post

The 91 to 61 scoreline is not unreasonable on a slightly wet windy day.

I suspect the magic figure is around 105 to 60 and we are equal with North on percentage,

IF we have a better percentage than north at the end of this round then we cannot miss the 8 on percentage.  

As Sue said, we still can. Percentages are not determined by difference but by a ratio. We could win and have our percentage go down, and lose and have it go up.

The point I guess is that if you have a percentage of 105%, your percentage will only stay the same if you beat your opponents by the same winning average, i.e. 5% (e.g. 105 to 100). If you win by a percentage lower than that, say 1% (101 to 100), then your percentage will go down, (and vice versa).

How much will depend on totals for/against, which pretty much depends on how far we are into the season. At this stage, high/low scores don't make much difference, but they'll still make some difference.

I think I have got it now

If we set off for Simmonds Stadium at 100% speed and the crowd average percentile is reasonable and Norths take on the name of an American rapper, we may make the finals, give or take a percent or two?

Which is?......he left the trench when it was under the most severe fire and ran, not very military, (unless you were an Argentinian conscript during the Falklands War)

How does such a corpulent monster of a human being like Phil Scully produce a progeny that is quite clearly a robot with no apparent vices whatsoever?

Some quick maths tells me if we were to score our season average of 87 points, to get near the Roos %age of 107.6, we'd need to restrict Carlton to roughly 35 points.

African or European percentage?

African percentage maybe, but not European percentage, that's my point.

Conclusion is true, but I go further and say that for extremely high scores your percentage can go down even if you win.

Let's say we beat Carlton 51 to 1, then our percentage after tomorrow is 107.6.  Then we beat Geelong by 120 to 119.  Total for =(1893+120)  total against =(1759+119), so percentage becomes (1893+120)  / (1759+119) = 107.2  It's gone down (!) and we miss the finals unless North's falls even further.  But if they lose by 1 point in a low scoring match say 40 points to 41, then their % becomes 1.074.  

I have used an extreme example for the Carlton match, but it will hold even truer for the other scorelines above.  It is possible to have the same % as North tomorrow or better, and also beat Geelong and we still don't get into the finals.  We need to win big in low scoring matches and we want North to lose big in high scoring matches.

Its round 22 and what a joy this is to see Demonland posters arguing about how much we need to win by to make up % to make the finals , instead of arguing about why we are still such a bad club we after another horrific end to a season.  Let the good times roll.

 

Couldn't agree more

[Adam The God 30,249]

We haven't really pummeled a team this year except the Suns the first time. Wouldn't that be wonderful tomorrow? Would keep it very simple next week. Can't see it happening though.

[Pates 9,660]

I guess this simply goes back to what Roos was saying earlier in the week. We stay focused on what we can control. Let's beat Carlton and beat them into the ground, come next week we can assess it then. 

Swans got the win over North so we're still alive.

Isn't Jeremy Cameron a lazy player. Bit full of himself I think. He goes to ground too easily and consistently takes the easy option.

Exactly. Essentially if you win a game with a lower percentage than your current overall season percentage - it will decrease. If you win a game with a higher percentage than your current overall season percentage - it will increase.

Yes - it's a proportion of total score, hence 'percentage'.  Nice illustration - makes the point very clear.  Also nice to know that it's really only the first three of those outcomes, and possibly the fourth, that are really plausible, and they all make a good dent in the percentage diff between us and North.   

So much at stake in this game that it's ridiculous.  So glad that we're still in the hunt, it would have been a real let down if the Swans had failed today.  We play twice now before North play their game against GWS, so the ball is well and truly in our court.

Exactly.  Basic algebra.

I don't think that is right.   North can lose without their percentage falling much (eg lose 2 points to 1 point).  But if we beat Geelong by 1 point in a high scoring game, then our percentage goes down from wherever it is after tomorrow.  Percentage can go down even if you win. You will have noticed this in round 2 of most seasons. The team that is on top after round 1 finds it's percentage heading down even when it WINS  the next week.

Edit to fix lose to WIN

 

Yeah OK, sorry cannot is the wrong word! But largely if our percentage is in front this week and results fall our way north will need the perfect set of circumstances involving margins and high/low scoring games to lose less percentage than we do and thus keep their spot. 

I acknowledge it is possible but it is so far fetched it is significantly unlikely!

 

But I'm glad at least a few people here understand enough maths for these discussions!
