Let me give an example of how the weighted version is scored to help clear things up a bit.
10 total sigs entered (Gym, Wiired, SSBB, KCBlack, Demonflair, tarheelsuperman, Close, CKNapp, Endlehach, Syntax)
Final voting (actual votes)
Ranking points before weight is added based on final voting
Now to add in the weight we would use the last 10 SOTW. So lets just consider that we have completed voting up to SOTW 19.
the wieghts would be like this
SOTW #10 would be ranking points times 1
SOTW #11 would be ranking points times 2
SOTW #12 would be ranking points times 3
SOTW #13 would be ranking points times 4
SOTW #14 would be ranking points times 5
SOTW #15 would be ranking points times 6
SOTW #16 would be ranking points times 7
SOTW #17 would be ranking points times 8
SOTW #18 would be ranking points times 9
SOTW #19 would be ranking points times 10
The weights would put more emphasis on recent work giving newly joining artist with talent a better opportunity to catch up as well as pushing those who haven't participated in a while down the rankings.
So for SOTW #14 the final weighted ranking score would be calculated as follows ranking points times weight of 5.
So for the final ranking we would add up all the weekly weighted ranks for the last 10 SOTWs (for our example SOTW 10 - 19) and then put them in order.
It's a tad more complicated than simple non weighted method but I think the rolling 10 week thing and the weights will help balance things out for talented newly joining artists.
Does that help clarify?
