Time balanced Zero Sum

[Jarlson]

Was wondering if there was a way to set up the log parser to handle the following system:

160 DKP is spent on items during a 20 main raid and people come in and out of the raid.

Person A Spent the full 4 hours in the raid
Person B Spent 3 hours in the raid
Person C Spent 1 hour in the raid

I would like to reward Person A with the full 8 DKP. (160 / 20)
Person B should get 3/4 of the DKP or 6.
Person C should get 1/4 of the DKP or 2.

Is there a way to set this up?

The formula for it would be:
Time spent in raid / Total time of raid * Zero-sum award

Any help on ideas to put this in or if there's already a way to do it would be appreciated.

The system you describe is not a zero-sum system since the total DKP earned will not equal 160 unless everyone is present during the entire raid.

The program's closest automatic thing to the system you describe is zero-sum per minute, which distributes DKP so that the DKP earned is proportional to the number of minutes spent in the raid (someone who spends twice as much time in the raid earns twice as much DKP) and maintains zero-sum.

Excellent! Not exactly what I was thinking, but accomplishes the same effect AND maintains zero-sum (as you said).

Thanks.
