"Winner will be chosen based on CSDB's rankings."
.. I'll take a look at scores at midnight (GMT) on 22nd January. Unless everyone disagrees, I'd like to just take a simple average of the score rather than the ranking - so I would total up the score and divide by the number of votes... no weighted algorithm. |

you'll make the downvoters happy with that. |

I haven't seen evidence that CSDb's weighted voting works all that well. Somebody pointed out to me that if there's a prize involved, and the scoring system is "behind closed doors" (a "secret" algorithm), then the result could be contested.
The prize is substantial on this one (1000Euro value)... so the "calculation" of who's won needs to be plain IMO. |

I recommend counting squared number of votes :) Really reliable, even if final average seems a little too sweet. No classic weights here. |

This sounds like a good idea. So something like:-
(((#10votes)^2 * 10) + ((#9votes)^2 * 9) + ... + ((#1votes)^2 * 1)) / ((#10votes)^2 + ... + (#1votes)^2)
That does seem to work well.
Check:-
Demo 1.. 20 people vote 10, 1 votes 1
Demo 2.. 20 people vote 1, 1 votes 10
Demo 1
Reg: (20 * 10 + 1 * 1) / 21 = 201 / 21 = 9.571
Squ: (20^2 * 10 + 1^2 * 1)/(20^2 + 1^2) = 4001/401 = 9.9775..
Demo 2
Reg: (1 * 10 + 20 * 1) / 21 = 30 / 21 = 1.428
Squ: (1^2 * 10 + 20^2 * 1)/(1^2 + 20^2) = 410/401 = 1.022
Ok, let's go with the squared calculation. Is everyone ok with this..? |

Yep, I'll use the squared calculation. Thanks Jammer for the idea. |

I've used it once already in my own compo but I was yet a bit afraid of utilizing it alone. Hence I mixed it with simple mean - now I regret a bit :D |

nb. I have the Mega65 now. Still fully boxed - I haven't even taken the sellotape off the box to have a peek. When the compo winner is decided, I'll arrange international (or national..?) delivery ASAP. Stamps Back of course ;-p |
