Hey Nath,
I'm not sure if it has changed in the past few season, but here is what I work on.
BE = Price x 3 / MN - last score - score before that.
eg Neale: 721,800 x 3 / 5,120 - 75 - 77 = 270.9
Projected price rises/falls are totally dependent on the players projected scores. I generally have no faith in projected scores, particularly Rookies, as they are just projected to score their average! I once saw a Projected Score on SC for Roughie to score 187, and he had never scored anything like that, to that stage of his career.
If a player has a BE of 100, and a projected score of 120, then his projected price rise (because his projected score is over his BE) is:
(120 - 100) x 440 = +$8,800
If a player has a BE of 140 and projected score of 90, then his projected price drop (because his projected score is under his BE) is:
(90 - 140) x 440 = -$22,000
A player is priced to score at his Price/MN. In Round 1 Neale is priced at basically his last years average, as is every player, except for rookies, or players that played less than 7 games. Players with less than 7 games get a discount on their price, depending on exactly how many games they played. Once the season is well underway, you can just use 5000 as a good approximate. Joe Bloggs is priced at $450,000, so he is priced to score at 450,000 / 5,000 = 90.
The MN changes quite dramatically after Round 3, when the first price rises hit. At this time it usually drops around 5%, but is largely dependent on how well the Rookies score. The higher the Rookies score, as a group, the more their prices rise, the more the MN drops. As the Rookies price rises become less dramatic, the MN drops less and less, until it gets to the stage it can actually fluctuate up and down a little. The MN started at 5,372 this season. A 5% drop would see it go to 5,103. I'm using 5,120 as an approximate, which happened to closely coincide with what SC are using.
I hope this has been helpful.

Hi Nath,
I'll have a go and I'm sure Rowsus will correct any shortcomings.
The formula for the prices in a normal season is NP = 0.75*OP + 0.25*(3 RD AVG)*MN
Where:
OP = Old Price (price going into the round you're looking at)
NP =New Price (price at the end of the round you're looking at
MN = Magic Number
MN is a number which varies between around $5,400/pt at the start of the year (Neale with an average of 134.4 is priced at $721,800, which would give you a starting MN of around $5,370/pt) and ends up around 4,900-ish.
It all depends on the year, the main thing is that it drops in season, the biggest drops coming in the early rds as the rookie prices rise (and the prices of the remaining players in the pool have to reduce to o***et and keep a constant Total Price Pool (TPP)
Looks like they are estimating a Magic Number around the $5,120/pt mark for next week, for example.
BE: The score at which the player's OP = NP
Using the formula above:
NP = OP = 0.75*OP + 0.25*(3 RD AVG)*MN
0.25*OP = 0.25*(3 RD AVG)*MN (cancel out the 0.25 on both sides)
OP = (3 RD AVG)*MN
OP/MN = 3 RD AVG
And the 3 RD AVG = (score of round n-2 + score of round n-1 + BE score of current round n)/3
OP/MN = (score of round n-2 + score of round n-1 + BE score of current round n)/3 (rearranging to isolate BE score of current rd)
3*OP/MN - (score of round n-2 + score of round n-1) = BE score of current round n
Using an example: Lachie Neale
OP = $721,800
MN = $5,120 (currently, roughly)
Score round n-2 =77
Score round n-1 = 75
3*721,800/5,120 - (77+75) = BE score of current rd 3 = 271
BE score of current rd = 271, which is what the SuperCoach site shows.
To figure out the expected MN in any one week, take a couple of players' BEs and work back the other way:
MN = (3*OP) / (score of round n-2 + score of round n-1 + BE score of current round n)
In terms of projected rise and fall, it's always about the difference between what you think they'll score and the BE.
If you think they'll go 30 higher than the BE of that week, for example:
NP(+30) = 0.75*OP + 0.25*(3 RD AVG B)*MN, where the 3 RD AVG B includes the +30 vs the BE and bumps the AVG up 10 pts.
NP(+30) - NP(BE) = 0.25 * MN * (Expected Score - BE score)/3 = 0.25 * MN * (30)/3
If you assume an MN of around $5,100/pt to make things simple, then you get (0.25 * 5,100/3) * (Expected Score - BE Score)
And (0.25*5,100/3) ends up at around $425/pt.
As a rough rule of thumb, take the differential between your expectation of their score minus the BE and multiply that by $425/pt to get a rough estimate of their increase / decrease. (You can make it more exact by calculating the actual current MN, but for a simple rule of thumb, the 425 will give you a good enough idea unless it's a really tight one. You can use 415 after about rd 6.
Lachie Neale:
BE: 271
Your expectation: Let's say 110
Expected Price Drop assuming $5,100/pt would be (110-271)pts * $425/pt = $-68,425 price change
(Expected Price Drop using the more accurate current MN would be (110-271)/3 * 0.25 * 5,120 = -68,694 price change)
Hope that helps and if I've buggered anything up, those smarter than me will correct it for you. Good luck

Amazing! Thanks so much guys for your responses! Just shows how good a game it is for Maths. I am a school teacher and I think they’re could be some good lessons in these and SC in general for maths/data/stats.
Thanks again for the detailed answers.. I will have a good read through! I wish they still had the “Rep” button on SCS!
Cheers,
Nath
