The weight applied to each challenge is computed as the product of how many games in the challenge TIMES decay factor. I am using 2 years as the data window, so that means that a war from 2 years ago has 0% decay factor (means does not affect score anymore), 1.5 years ago has 25% decay factor, 1 year ago has 50% as decay factor, 6 months ago would be 75% as decay factor, yesterday would be 100% decay factor.

I can change data window from 2 years to any other integer without having to modify my code - it is a parameter that you can change by typing in an input box.

First time I'm seeing this Farang, so I apologize for being late. EMPIRE's round 5 games were us completely destroying BPB. I noticed they got the massive win credit. That should be changed. If memory serves, we ended with the 2nd best record, only a few games behind TOFU. Now, the play-offs were another story. :cry:

Never mind. Just noticed I was in the archives. How did that happen?

Why didn't you merge the threads?

Because the OP in this one is older than the other and would have taken Farang a lot of work to sort it out. Noone had posted in this one for 3 months. I will merge them if that is what Farang wants me to do, since they are both his thread.

I'm send him a PM
