How are wiki edit points assigned?

What I mean is how is it decided how many points a submission is worth? Does the moderator just decided or is there a set system? I'm just wondering cause I can't make sense of some of the point scores I've received. 
Thanks

The number of points you're awards is determined automatically by the amount and type of content.

More points for less work can easily happen if that work involves adding things with lots of HTML tags. You can't see them while you're editing, but that extra HTML can cause the size of the page to increase significantly.

Is there any way editing could be worth more? I spent about an hour cleaning up the GTA IV page today, 2nd to 3rd person, future tense to past re: DLC, bad writing to not-bad writing, etc., and got one point for it. It's not like this diminishes my e-peen or anything, it's just that I would like to reach that 1,000 points, edit without approval threshold one day, and that's a very long row to hoe one point at a time.

" @edlund:  Yeah, it's kind of weird. I completely rewrote a few sections that were just false, but they ended up being shorter. Only got one point for those. Just got my first big edit today though, 320 points for not that much work, so 1,000 points totally seems within reason when purely adding content. "

" and i corrected a SINGLE misspelled word in one wiki and got 5 points for it... maybe the system just doesnt like you guys =p "

Anyone looking to get the 1,000 point one, check out the Rally Cross one I wrote.  Before I found it there was two or three sentences, I added all the rest, earned just over 1,000. 
 
Also, try adding picture FIRST.  That way you can add in pictures with captions and earn points while editing. 
 
Also, like others have said, to get the 1,000 point one, find a game that is a little less popular that you really liked, and write about it.  Keep in mind that brief level summaries can be added, lists of weapons and items, lists and descriptions (with pictures!) of the characters, and information about the scoring mechanics.  These are all good areas to fill out that don't require much technical or special skill.  Also, this site isn't like Wikipedia, you can have a section for "Trivia" or "Easter Eggs." 
 
Also, I usually spend a little bit of time discussing interesting gameplay mechanics.  In my opinion (and I'm not a mod, so take this with a grain of salt) GB likes good information unique to the game, but is less interested in 1) your re-typing of the instruction manual and 2) talking about how the game uses 100 hitpoints to measure your health. 
 
I have done some pretty serious edits to concept pages, and never been able to hit 1,000.  I wrote the entire Fictional Car Brands one and got about 600.  I think I got close with Tie-In, but I put a lot of links in.  Rally Cross was a good for me, like others have said, because it had an empty page, and was a game I spent a ton of time with and new a lot about.  I actually had to turn on my PSX to remember a few of the car names, but most of that I wrote from memory.  Try to think of a game you spent a lot of time playing through, possibly from an older generation, and see how much is in the current wiki.  Also, take some time to think about what you might write, and leave yourself some time.  The Rally Cross one took me about an hour and 15 minutes.  Tie-In took close to two hours, as did Fictional Car Brands.  Death, which scored me 800, was fairly quick, but still took close to an hour.  It is worth it though, I felt awesome getting the achievement and it feels good to help fill out the Wiki.  Perhaps one day GB will be the ultimate source of videogame knowledge, and you can have a part in it.

They are assigned in a very broken way...doing things such as adding images within the article awards more points than actually writing stuff which is why a lot of wiki pages have a lot of pictures within the article....they really need to fix the point system....also another case of a new user necroposting.

the wiki gods hand them out. They enjoy long paragraphes and links.

I just got 5 points for changing an 'a' to an 'an' on the LA Noire page. I'm pretty sure it's up to the moderator.
