ROW IV Scoring??

[Mad Russian]

Can somebody tell me how the scoring is done? I thought initially that there was some intricate score done on the AAR page that took into account how you actually did vs the other players. But now it appears that it may just be the Tactical Victory at the end.

I am confused. Is there a simple answer to this?

It could be very important at the moment.

See http://www.bootsandtracks.com/ROWRules.php#scoring for details.

Bottom line is you just should score as well as possible in all your games.

Correct

Yes, there is. Go here, scroll halfway down and read the section titled 'The Modified Nabla scoring system'. This will give you a basic understanding of how the scenario score (the one you send to me) is taken, then compared to all the others scores of the same scenario and side, then calculated to achieve your tournament score.

Keep in mind that this scoring system is being updated as we speak to include the full Nabla program, not just the modified version.

So, to answer your question, your tournament score is much more than just the tactical victory that the scenario awards you. That is only taking into account how you did against your opponent. In this tournament you must also do better than the other 35 players.

Of course that is true but some are better than others.

When you are up to your eyes in alligators, it is sometimes hard to remember, that the original objective was to drain the swamp!!

Man have I got alligators!!

Thanks for the response.

No, the Nabla system takes into account how difficult the scenario was to play the side you played. If you get a tac defeat and everyone else was totally defeated, then you do very well in the tourney even though you didn't win the scenario...

Trust me, if the Nabla system was nothing more than a straight average then Jarmo and Treeburst wouldn't have bothered writing this.

Here is the nuts and bolts of how the tournament is scored, which btw is copied from the manual I listed above:

This is what the scoring program does:

1. It rst looks for scores that do not add up to 100 due to contested/unoccupied

VLs, and split the dierence between the players equally (this is for

CMBO, note that in CMBB CM points always total 100). For exam-

ple, a nal score of 70-20 would be converted to 75-25. Scores will

always add up to 100 after this adjustment. There is a very good

reason for doing this involving agreements between players designed

to maximize their scores. Perhaps you can gure it out?

2. The median score for each side of all the scenarios is determined.

3. The dierence between a player's score and the median score for the

side he played will be determined for all scenarios.

4. The standard deviations from the median scores are determined for all

scenarios. This value will always be the same for both sides of a given

scenario due to step 1 above.

5. The dierence from the median will then be divided by the standard

deviation resulting in the \normalized dierence from the median".

6. The normalized dierence from the median is then assigned a Nabla

score for the scenario. This is done with a formula created by Nabla

that is at work inside the scoring program.

7. The average of all a player's Nabla scores (one for each scenario) is

then determined, resulting in the player's nal tourney score. The

high score in each section is the winner of the section.

Step #1 is really not needed, as all scores add up to 100% in CMAK.
