PWC 2009 Scoring System

[luciano.gallo]

<p>Dear all!<br />
Is there anybody devoloping (or thinking to develope) a score module for PWC 2009 Scoring System for FS ?

Looking into it, seems the specifications is not fixed yet, only a draft in the 2009 rules and this is not very well described either.

If anyone can clarify it would be good.

I have worked out how the PWC 2009 scoring formula is intended to work now (I think).

The base of it is GAP.

After scoring with GAP the following takes place:

– tasks with winner GAP score >=700 gives 1000 PWC points to the winner (the other scores adjusted accordingly).
– tasks with winner GAP score <=200 gives 0 PWC points to the winner (and the rest), ie the task does not count anywhere.
– tasks with winner GAP score >200 & <700 gives from 4 to 1000 PWC points to > the winner using the formula (x-B)(2*A-B-x)/(A-B)^2) where x is winner GAP score, A=700, B=200 (the other scores adjusted accordingly).

So, this is simple to achive, but why to do it I’m not sure…

In reality it is just a way to change the behaviour of the Day Quality calculation that GAP does (based on nom. dist., time, goal).

It is not clear (from the rules or the comp reports) what GAP parameters are used.

It does look like they used
– Distance Points
– Time Points
– Leading Points
– Arrival Time Points / 2 !!
– Min. Dist = 5
in Korea.

“- Arrival Time Points / 2 !!”

Actually they have, by design or error, used the OzGAP2005 style Arrival Time Points but with a twist:

m_fAvailableScoreArrival = 1000# * m_fDayQuality * (1 - m_fDistanceWeight) * 1 / 8

(as used in normal GAP Arrival Position Points) instead of

m_fAvailableScoreArrival = 1000# * m_fDayQuality * (1 - m_fDistanceWeight) * 1 / 4

which is used by OzGAP2005.

Does anyone have the task definitions for the PWC that was i Brazil?
