[ Discussion ] On scoring the weekly challenges

I wanted to ask what you think of a possible change to the scoring of the weekly challenges.
Right now most of the scoring is based on who gets the most upvotes. It works well for keeping things impartial, but those who post early will get more views and more chances at being upvoted than those who post later.
We already try to make things fairer by awarding bonus points to the last two images and a penalty for posting within the first 24 hours.
That last one got some feedback with some valid points, so I would like to suggest something different.

I want to see if having a separate submission and scoring post might work for the next challenge. Everyone can submit their images for at least 7 days and then I put them all together in a new post with separate replies to let people vote for at least 24 hours. Maybe even wait with posting until the weekend to get the most out of it?
I'd be happy to hear your input on this. It's a bit more work, but I don't mind doing it if it makes things more fair. And I hope I can automate the tedious stuff.

Nothing much changes on your end, but it might make the whole experience more fun and less of a race :)

edit

Thank you so much for your input and appreciation. I've heard some great arguments and will keep these in mind.
I'm going to give this a try for the coming challenge. But to whoever wins next, feel free to ignore all of this and try something different for the challenge after this.
Just know I'm always happy to help out in whatever way possible.
