weighted average?
ok something i just noticed when i was voting for alih.
the guy has 6 9's and 3 8's and a 1 from a downvoter. his weighted average turns out to be 7.7.
now if we took the arithmetic average. it would be
(6 x 9) + (3 x 8) + 1 = 79 divided by 10 would be ~ 7.9
so the weighted average function was supposed to be able to recognize downvoting and perform better than arithmetic average. I say something is wrong.
not only the real average should have been somewhere in high 8's, but also the csdb function works even worse than the arithmetic average.
am i making a calculation mistake or something? |

Just checking if my alteration made people with only bad votes get a rating of 15 or something. ;P
But except for the two people with very few votes (always hard to do a good calculation on few data), I can't see that the rating calculated is unfair, so Graham & Crossbow better shape up! ;);) |

It's still a bit odd to see a MacGyver in the Cracker charts, though he is a pr manager (with 1.7 as vote).. |

I guess the charts on CSDB can only be taken as serious as those who lodged the votes to begin with. ;)
Charts these days are a laugh, a real shame some old-style scene chart/website is not compiled/created. It may stir some competition or provoke some motivation. |

there needs to be a present chart like it is supposed to be on diskmags. a chart where someone who has not released anything for a certain time should be left out of.

i think instead of 5 votes a production, person or group should get 10 votes to be entered in the charts. there are enough users nowadays, and someone with only 5 votes usually ends up at a place where they dont belong. |

I though about something similar. This would make the charts a bit more realistic, but on the other hand a lot of entries will be removed from the charts. (The ones with 5-9 votes)
Anyone against the idea? |

10 seems to be a good number.
perff. do you ever plan to make a chart where inactive people are dropped after a certain time? |

No, not really. I always though of the CSDb charts as a kind of all-time-chart. |

It would be nice to add something like number of voters in the calculation.. Popularity is also important, the more votes, the popular the guy/girl.. |
