Ok so you have to vote on %20 of the total of the pictures in order for your vote to count, but doesnt it count from the moment you vote?
Say that 2 people in totall voted for my picture, the first votes a 10 and the second votes and 8, that would leave me an average of 9.
That nine is posted under my submission and i can see that i have 2 votes that average a 9.
Now what if that first person only voted for %15 of the totall pictures, then does that vote still count for me or is that vote taken off when voting ends leaving me with an 8?
Just curious.

I think you answered your own question: "you have to vote on 20% of the total of the pictures for your vote to count". At the end of the challenge, the vote is removed from your total if the voter failed to vote on at least 20% of the submissions.

The votes should only affect the image scores once the 20% mark has been reached - thus if someone only votes on 19%, then the images they have voted upon will see no change in score (until they go over the 20% line).

Hmmmm... Then how can we see scores so quickly right after the challenge begins? Surely, with 600+ entries, noone was able to vote on 120 images in 5 minutes (when I saw the first votes come in on my entry), ...I wouldn't think anyway.

At 5 seconds an image, 120 images would only take 10 minutes...

Are you sure about that, Manic? Logic tells me that if, at the end the challenge, the vote total on my image is reduced because a voter failed to meet the 20% minimum, then that person's vote was reflected in the vote count and average score prior to being removed.

I'm fairly certain the votes count immediately, and anybody who didn't reach the 20% minimum has their votes removed during the "Computing Results" stage...

Strange, thought it was an ongoing thing, rather than at challenge rollover. Guess I'm getting confused with sommat else :o)

I always understood that it worked like Eddy described. So if it's midnight at the time a new challenge begins, you'll still see those first few votes and the scores so far... but those can be negated when the results are computed at the end of the voting period if the voter didn't do the 20%.

therefore my little hint.
If you want to vote on JUST the 20% of pics, then in order for your votes not to be removed you should vote a few more than needed. That is in case a few of those you already voted get DQ'd.
Not a problem for me. I tend to vote on all.

That would make sense to me.

All images voted upon, including DQ'd images, count towards the 20%.

Here is where it gets confusing...

Let's say a challenge has 200 entries at the beginning. During the course of the week, 10 get disqualified, leaving (what appears to be according to the front page) 190 entries.

The way it is implemented today, somebody who goes in to vote on the last day needs to vote on 40 entries -- not 38 -- in order for their votes to count, since it is based on the total number of entries.

This is an unfortunate side effect of the opposite problem, where the 20% rule would be based on the number of non-disqualified entries (which seems like the better approach). But with that implementation, take, for example, a 200-entry challenge where somebody voted on exactly 40 entries (20%) on the first day of voting. By the end of the week, 2 entries are disqualified, both of which happen to have been part of the 40 votes cast by that user earlier in the week. That now leaves them with votes on only 19% of the non-DQ'd shots, meaning their votes won't be counted -- even though they thought they had voted on 20% of the entries...

I'm thinking the votes from the people that didn't vote on 20% are counted until the end.
How else do you explain votes showing up minutes after the challenge started and the score often rising by .1-.2 the second after the scores are calculated?
I think it would be easier to do the math at the end also, rather then doing it constantly. It would mean a calculation would be done on every vote by every person, rather then once at the end. And then there would also need to be a buffer memory to hold the votes from the less then 20% voters that don'r count yet... Sounds like a nightmare to do it that way, but my programming skills are limited so I might be wrong on that.

Those may be from people who voted on 20% of the images, but with such a voting pattern as to make the vote-purging algorithm discard their votes. This would also explain why the vote is virtually always bumped UP in the final calculation, as it is probably an excessive number of very low votes which triggered the purge in the first place.
