We made some changes to how Player Points are calculated today. Player point calculations now take these into account: Number of ratings a movie has had The Tier the movie has been published to. Player points reflect this change now. You may notice some published author's have more points, and some have less. For those curious, the number of ratings is done with a bell curve distribution, with a peak at the average number of ratings. Tiers are done as a multiplier. Currently the multipliers are .75 for vault, 1 for moon, 1.5 for star. Also player points now are calculated and stored rather than calculated on the fly. The numbers updated once per hour. So you will not see an immediate change in player points when movies are published or rated.

Sounds like a good and fair system. I like that the vault multiplier is less than 1 as an incentive for authors to shoot for making entertaining (Moon) runs.

Does this mean the site will noticeably get very slow every hour?

The script runs in like 2.5 seconds.

I hope so. I want authors to feel that if put in every effort to entertain the audience, they will be rewarded with a higher tier, and more points.

No, if anything, the site will be faster, since it is not calculating these numbers on the fly constantly.

On 11/24/2012 ~ 1150 Points On 11/25/2012 ~ 600 Points Rough. Edit: Though I see why the change was made it just stung a little to see such a drastic change when all but 2 of my runs had been accepted under the old rules and one of those two had a 6.6 with 3.5 votes.

Any plans about vote weights?
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

That is an issue with how the average rating is calculated, a formula we have not altered with this change. As for plans to do so, not currently.

Oh, and side effect that script has: It assigns player ranks to those who have gotten a movie (removing isn't implemented). Team entries still have to be edited. Nice, as publishers quite frequently sometimes forget to assign those. And seeing missing player rank isn't easy, whereas seeing missing team entries is. (Player-List, and hit /(!) ) Also, now any current movie gives minimum of 5 points, no matter the tier or rating. This is to guarantee that you don't get former players with current movies and similar things. Also, having the script assign the ranks avoids that "unknown rank" bug, where user has player rank show as "unknown rank".

What is the exact player point formula now? I'm interested in knowing.

Yeah, I'd like to know it as well.

Ilari told me about the formula on IRC:
[17:46] <Ilari> FractalFusion: Well, the formula is: r^(2.6-0.2*average_rating_count/rating_count)/sqrt(p). Note that average_rating_count and rating_count count each tech and entertainment rating as one rating, instead of 0.5 like movie pages). r is weighted average (not weighted average of averages).
[17:47] <Ilari> FractalFusion: If exponent is smaller than 1, it is forced to 1. If result is smaller than 5, it is forced to 5. Obsolete movies get points multiplied by 10^-6.
[17:48] <Ilari> FractalFusion: Oh, and movie author ratings are ignored for averages but not for rating counts.
[17:50] <Ilari> FractalFusion: Furthermore, stars have multiplier of 1.5, moons has 1, vault has 0.75. So the absolute maximum score per movie is about 597.
Not sure what the "bell curve distribution" was supposed to mean, but don't worry about it.
