Thanks for pointing it out. I'm working out a fix for it now.

Actually, I have noticed some weird math in the average figures in our profiles. In the past 3 weeks I have not entered any challenge, yet my average received score has decreased. Not by much, but there is a change in it for sure.

My son and my husband's profiles have the same occurence. Can you please check this as well?

Thanks much.

I think that the average score is changeing because some pictures are disqualifed and removed from past challenges.
Some voters who voted 19% of the pictures before any DQ have for example 21% of pictures voted after DQ and their votes count now and that changes the scores because DPC calculation unit is built so (just a theory) :S

In my opinion this is absurd that scores are changeing after deadline of the challenge! Futhermore, in some RARE cases it might change the final order of pictures - e.g. first and second place swap positions :[

I could see having a photo removed and those below it move up but to move a photo move down or a ribbon swap places as you've described just sounds so very wrong. I would be very annoyed if it happened to me.

I believe there's been one tie for the ribbons so far so it could happen.

My feeling is that a DQ which occurs after the challenge (and therefore the voting) ends should NOT mean that votes that were not counted are now counted and votes that weren't counted now are (because of the 20% rule).

It should be that you need to vote on 20% of the photos according to the number of images at time of challenge, not later, following DQs.

That's just MHO anyway.
