Should be fairly easy to do since beatmap ranking is cached in the database.
Where do you think it should be displayed? Profile?

Yeah, that's how I originally imagined it.peppy wrote:
I think he means it would be a new Rankings page under that top heading, with people ranked according to their average rating.
Yes, I suspected that could cause some weirdness, but my math knowledge wasn't enough to suggest a formula to address this.peppy also wrote:
There would have to be some weighting given depending on how many maps you have total, as well. I think the scale would not be a fixed one (ie. not /10) for this reason - otherwise we will get people with a single map coming first above all the others with 50 odd maps made (hi eiji).
I can imagine Saturos going beatmap crazy trying to improve his beatmapper ranking.Sinistro wrote:
Maybe each beatmap after the first gets a (smallish) bonus multiplier to its rating...
Yes, I can imagine that too.chan wrote:

I can imagine Saturos going beatmap crazy trying to improve his beatmapper ranking.I can't. ;x

only ranked beatmaps should be counted towards the beatmapper ranking.
This ranking is based on a weighted average of all your ranked maps, with a bonus proportional to the number of ranked maps you have.I still don't get this, is it any related to the star rating? If it is, I should stop putting 10s on any beatmap that needs a rating
Its based mostly on star ratings, yes. So start rating properly >:|James wrote:

Wait a moment, that's just the average, right? Isn't the weighted average of the ratings supposed to be the sum of the products of each beatmap's rating times its number of ratings, divided by the total number of ratings, as in:peppy wrote:
The formula used is:
(sumRatings / numberOfRatings) * (1 + 0.03ish * numberOfMapsRanked)
No, it doesn't. With the above formula my score would be about 8,50 instead of 8,57 and awp's about 9,82 instead of 9,99, for example. I'm not sure in which way or by how much other scores would change. I believe weighting by number of votes is needed because I think the more people have voted for a beatmap, the more "consolidated" its rating is, if that makes sense.peppy wrote:
pretty sure it works out to the exact same number.
Weird...why do I see different ratings and vote totals for Aliento's beatmaps? Specifically, 7.5*145, 7.9*68 and 7.1*52, ultimately resulting in a rating of about 8.2013.Saturos wrote:
I did Aliento's rating using that formula really quick:
[(Rating for map #1 * map #1's number of votes) + (Rating for map #2 * map #2's number of votes) + (Rating for map #3 * map #3's number of votes)] / Sum ofPlay countsVotes = Avg weighted rating
[(7.9*120) + (8.3*44) + (8.1*75)] / (120+44+75) = Avg weighted rating
[948 + 365.2 + 607.5] / (120+44+75) = Avg weighted rating
1920.7 / 239 = Avg weighted rating
Avg Weighted Rating = 8.0364
EDIT: Seems Sinistro beat me to the post, but I gotz teh mathz0rz.
Yeah, when I said "with the above formula" earlier I got a little sloppy in my expression; I actually meant the formula of the weighted average I posted with the ranked beatmap bonus multiplier, which I had left off to focus on the formula's first part. To be precise, my proposal for the beatmapper ranking formula is:Saturos wrote:
Nah, that formula will always remain a number between 0-10, based solely on the ratings.
Just to be clear, that was directed at peppy, not you. ;xSinistro wrote:

[(Rating for map #1 * map #1's number of votes) + (Rating for map #2 * map #2's number of votes) etc.../Total number of votes for all of the beatmapper's maps] * (1 + 0.03ish * numberOfMapsRanked)
Fixed. I really need to sleep :/.Sinistro wrote:
It's under Rankings. You might need to refresh your page, like I did.
[nitpick] "Player" and "Mod" are in singular, but "Mappers" is in plural. [/nitpick]
There is no autoupdate code in place (blame me for being lazy)... should be up in a while.Sinistro wrote:
Are the ranking scores being updated with each new vote?
